Negative Exponent If n is a positive integer and a≠0 a ≠ 0 , then a−n=1an a − n = 1 a n . The negative exponent tells us to re-write the expression by taking the reciprocal of the base and then changing the sign of the exponent. Any expression that has negative exponents is not considered to be in simplest form.

Step 1: Set the expression inside the square root greater than or equal to zero. Step 2: Solve the equation found in step 1. In this case, we divided by a negative number, so had to reverse the direction of the inequality symbol. Step 3: Write the answer using interval notation.

Exponents can be used in a variety of ways to represent length. Specifically, negative exponents are used to represent how small something is. Bats, for example, are pretty tiny creatures. Zoologists use negative exponents to measure different parts of bats, such as their wingspan.

If any number is a solution to an equation or inequality, as in x² ≥ 0, then we write ℝ in set notation (“all real numbers”) or (−∞, ∞) in interval notation. If no number is a solution, as in x² = −5, then we write ∅ in either notation.

The Exception: Negative Numbers There is one very important exception to the rule that multiplying or dividing an inequality is the same as multiplying or dividing an equation. Whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign.

Put in the base number e on both sides of the equation. e and ln cancel each other out leaving us with a quadratic equation. x = 0 is impossible as there is no way of writing 0 as a power. Write the left side as one logarithm.

In a fractional exponent, the numerator is the power to which the number should be taken and the denominator is the root which should be taken. A negative fractional exponent works just like an ordinary negative exponent. ...

If your set includes negative numbers, the range will still be positive because subtracting a negative is the same as adding. Range is -4 - (-11) = -4 + 11 = 7. When dealing with range, imagine the numbers on the number line. The range is simply the space between the two extreme values.

Explanation: Write log7(12401)=−4 as an exponential. Note that the 7 is the base of the log and the base of the exponential. And, the "answer" to a log equation is the exponent of the exponential.

When you are adding a negative number to a negative number, it becomes subtraction, where you start from a negative point on the numbers line and move left. For example, -3 + (-2). This reads “negative three plus negative 2”.
