how is 3*10to the 8th power written in standard form?
82291
As in 3*100,000,000 or as in 300,000,000?

it would actually be 4.3927  x  10 to the 3rd power.\n\nyou move the decimal over so that there is only one digit before it, and then you get that # and multiply it by 10 to (the amount of spaces the decimal moved to the left) power.\n\nif it is something such as 0.00043927, then it would be 4.3927  x  10 to the -4th power. when you move the decimal to the right, the power is negative.

3 to the 5th power\nor 3*3*3*3*3

i dunno if i use it correctly but sometimes when i have to do like, a math project i use it to say for example:\n10 to the 6th power but instead of writing it all out i write:\n10^6 \n\nget me?\nhmm. good luck on finding the answer!

Are you able to use any other numbers and operators?  If so this would be fairly easy.  Using only Three 8's and a subtraction symbol it is not possibe\n\nClosest example (8+8)/8-1=1

it is radical 8\nrt8 or 2.828

There are a couple of ways to work this out, I will take the easiest to explain.\n\n(x-3)(x^3+3x^2+9x+27) Can be rewritten as:\n\n(x)(x^3+3x^2+9x+27)+(-3)(x^3+3x^2+9x+27) Now, multiply those out.\n\nx^4+3x^3+9x^2+27x-3x^3-9x^2-27x-81 Now, sort by like powers of x\n\nx^4+3x^3-3x^3+9x^2-9x^2+27x-27x-81 Simplify\n\nx^4-81

There is no sign for exponent in your question.  I assume you mean\n2^(3/5)\nAny expression of the from x^(m/n) can be written as the\nnth root of x^m\nThus, 2^(3/5) is the fifth root of 2^3 which simplifies to \nthe fifth root of 8.

Let n_b denote "n base b"\n\nAre you converting 653_10 to another base, or converting 653_b to base 10?\n\nTo convert 653_b to base 10, you simply have to add up 6b^2+5b+3.\n\nTo convert 653_10 to another base b, you have to find the greatest power of b that goes into 653, and how many times it goes in. You write this down as the k+1 digit, where k was the power of b being raised. You then subtract how many times it goes in times b^k, and repeat. For example...\n\nCovert 653_10 to base 3.\n\nThe greatest power of 3 that goes in 653 is 3^5, which equals 243. 243 goes into 653 two times, so we subtract 2*243 from 653. 653-486=167. Our number is now of form 2 _ _ _ _ _.\n\nThe next power of 3 is 3^4, which equals 81. 81 goes into 167 two times, so we subtract 2*81 from 167. 167-162=5. Our number is now of form 2 2 _ _ _ _.\n\nThe next power of 3 is 3^3, which equals 27. 27 goes into 5 zero times, so we subtract 0*27 from 5. 5-0=5. Our number is now of form 2 2 0 _ _ _.\n\nThe next power of 3 is 3^2, which equals 9. 9 goes into 5 zero times, so we subtract 0*9 from 5. 5-0=5. Our number is now of form 2 2 0 0 _ _.\n\nThe next power of 3 is 3^1, which equals 3. 3 goes into 5 one time, so we subtract 1*3 from 5. 5-3=2. Our number is now of form 2 2 0 0 1 _.\n\nThe final power of 3 is 3^0, which equals 1. 1 goes into 2 two times, so our final number is 2 2 0 0 1 2.\n\nTo check, we simply convert 220012_3 back to base 10 using the method above.

(8y^3 + 27)/(2xy - 10y + 3x - 15)\n((2y + 3)(4y^2 - 6y + 9))/((2xy - 10y) + (3x - 15))\n((2y + 3)(4y^2 - 6y + 9))/(2y(x - 5) + 3(x - 5))\n((2y + 3)(4y^2 - 6y + 9))/((2y + 3)(x - 5))\nthe (2y + 3)s cancel out\n(4y^2 - 6y + 9)/(x - 5)\n\nANS : (4y^2 - 6y + 9)/(x - 5)

It means power of 10 (it's a shorthand for scientific notation).\n\nSo your equation is:\n\n(1*10^-230)*e^(0.2682*x)\n\nWhere lower case e is the mathematical constant e (2.718...).

It's multiplication.\n\n(64500)(0.02) = 1290\n\nScientific notation is 1.29 * 10^3

Every time that we move the decimal point to the left, we are dividing a number by 10. we can make up for this by decreasing the power of the exponent by 1.\n\nEvery time that we move the decimal point to the right, we are multiplying a number by 10. we can make up for this by increasing the power of the exponent.\n\n\n.0035 x 10^15 = 3.5 x 10^12\n.002 x 10^17 = 2 x 10^14\n\n7000 x 10^33 = 7 x 10^36\n\nWhen multiplying two scientific notation numbers, like\n\n(a x 10^b) * (c x 10^d)\n\nmultiply a and c, and add b and d. Use the sum as the exponent of the product.\n\nSo:\n\n(3.5 x 10^12) * (2 x 10^14) = 7 x 10^26\n\nNow we can divide.\n\nWhen dividing two scientific notation numbers, like\n\n(a x 10^b) / (c x 10^d)\n\ndivide a by  c, and subtract d from b. Use the difference as the exponent of the product.\n\nSo:\n\n(7 x 10^26) / (7 x 10^36) = 1 x 10^(-10)

It is just like your other question.\n3*8*6 = 144

The 8.198 part is called the mantissa.  The "5" in 10^5 is the exponent.  Shift the decimal in the mantissa the same number of places as the exponent.  Shift right for positive exponents, left for negative ones.\n\nSo, you have the right answer, 819,800.

It is based on powers of 2.\n\ni.e. 2 ^ 10 = 1024

That'd be 3x^2-10x-3\n\nNOT -3x on the end, just -3
