A rational number is a real number that can be written as a ratio of two integers. 0.1 and 1/3 are rational numbers. \nNumbers that cannot be written as ratios of two integers are called irrational. The square root of 2 is not rational, and there is a cute little proof of this fact. 1/0 is not a rational number because it is not a real number. Pi (the ratio of a circle's diameter to its circumference) is also irrational.

900. these are al squared numbers. 100=10x10; 3600=60x60; 400=20x20; 900=30x30

is 9/3=3\nsee 3x3=9\nsquare means multiply the number by its self.\nso 3 square is 3\nget it?\nhope thats what you wanted.

Actually, that's the approximation. The exact answer is: square root of 223423423432435. Of course I can't be sure because I've never heard of a mathematical operator called the "square route." I've heard of roots in mathematics, but not routes!

1 followed by 10^50 zeros\n\nSince a googolplex (notice it's googol, not google like the search engine) is a 1 followed by 10^100 zeros, the square root of that is just half the exponents; just like sq.rt. of x^2n = x^n.\n\n~ ♥ ~

When working with the simplification of radicals you must remember some basic information about perfect square numbers. \n\nYou need to remember:  \n\nPerfect Squares \n4 = 2 x 2 \n9 = 3 x 3 \n16 = 4 x 4 \n25 = 5 x 5 \n36 = 6 x 6 \n49 = 7 x 7 \n64 = 8 x 8  \n81 = 9 x 9  \n100 = 10 x 10 \n \n Radicals (square roots) \n = 2 \n = 3 \n = 4 \n = 5 \n = 6 \n = 7 \n = 8 \n = 9 \n = 10 \n \n \n\nWhile there are certainly many more perfect squares, the ones appearing in the charts above are the ones most commonly used. \n\n \n\nTo simplify means to find another expression with the same value.  It does not mean to find a decimal approximation.\n \n\n \n\nTo simplify (or reduce) a radical: \n\n1.  find the largest perfect square which will divide evenly into the number under your radical sign.  This means that when you divide, you get no remainders, no decimals, no fractions.\n\nReduce:  the largest perfect square that divides evenly into 48 is 16. \nIf the number under your radical cannot be divided evenly by any of the perfect squares, your radical is already in simplest form and cannot be reduced further.\n\nwrite the number appearing under your radical as the product (multiplication) of the perfect square and your answer from dividing.\n\n\n \n\n3.  give each number in the product its own radical sign.\n\n\n \n\n4.  reduce the "perfect" radical which you have now created.\n\n\n\n5.  you now have your answer.

A building square is defined as an area\nof 10 feet by 10 feet, or 100 square feet.\nThis is equivalent to 9.29 square metres.

The square root of negative 1 is the number, which multiplied by itself, gives negative 1.  Any real positive number when multiplied by itself gives a positive number.  Any real negative number when multiplied by itself gives a positive number.  Therefore no real number can be the square root of negative 1.\n\nHowever, it is useful to create a system of mathematics where negative one has a square root.  To do this we think of all the real numbers as belonging to a line.  We create another line, perpendicular to this line, and intersecting at zero.  We call this line the imaginary axis.  Then we invent rules for multiplying points in the plane defined by the real axis and the imaginary axis.  The way mathematicians have defined these things, the unit 1 on the positive imaginary axis when multiplied by itself is equal to negative 1.

Mathematicians have designated a special number 'i' which is equal to the square root of minus 1. Then, it follows that i2 = -1. To determine the square root of a negative number (-16 for example), take the square root of the absolute value of the number (square root of 16 = 4) and then multiply it by 'i'. So, the square root of -16 is 4i.\nAs a double check, we can square 4i (4*4 = 16 and i*i =-1), producing -16.\nAll negative square roots are called "imaginary numbers" (now you know where that letter 'i' comes from).

This seems to be a popular question. There is no real number that is the square root of -1.  However, it turns out that it is useful to develop as set of numbers that allows the square root of -1.    This is called "i" as is known as an imaginary number.  The set of numbers that includes i is called the set of complex numbers.

-7 and -sqrt49\n\nYou can not take a square root of a negative number. Well, you can, but it's called an imaginary number because it can't actually exist.

Radical numbers are ones you are taking a root of.  The square root of 2, written as sqrt(2) (really written with that thing that looks like a long division sign).\n\nYou can take higher roots of numbers - cube root, for example, would look like a square root of a number, but with a 3 in the upper left of the outside of the sign (the 2 for a square root is omitted, and it is understood that if there is a square root sign with no number in that top left corner, then it is a square root).

answer is 49,  49 is a square root!!

Yes. A square has an order of rotational symmetry of 4. \nThis means that if you were to rotate a square 360 degrees (1 complete revolution) about the intersection of its diagonals, you will get 4 as the number of times it takes on the initial form in terms of position and alignment.

The square root of a negative number is an imaginary one.  The square root of -1 is known as i.  Negative square roots work out like positive ones, only with the i, so SqRoot(-4) = 2i and SqRoot(-64) = 8i.
