## How do parentheses affect exponents?

Explanation: An exponent outside of a parentheses means the entire quantity is being raised to that power. In other words, the quantity inside the parentheses is being multiplied by itself the number of times the outside exponent says. Recall that when like bases are being multiplied together their exponents are added.

### Do parentheses matter in exponents?

An exponent applies only to the value to its immediate left. When a quantity in parentheses is raised to a power, the exponent applies to everything inside the parentheses. Simplify the expression, keeping the answer in exponential notation.

#### What do you do with negative exponents outside parentheses?

I’ll start by noting that the negative exponent on the outside of the parentheses means that the numerator should be moved underneath and the denominator should be moved on top. In other words, the fraction inside the parentheses should be flipped.

**What is the difference between parentheses and no parentheses in exponents?**

If the base is in parentheses, as in our first case, the exponent affects everything that is inside the parenthesis, that is, the sign and the number. However, if the base is not in parentheses, as in the second case, the exponent affects only the immediate value to the left, that is, only the number, without the sign.

**Why is a negative squared still negative?**

“This is because to square a number just means to multiply it by itself. For example, (−2) squared is (−2)(−2)=4. Note that this is positive because when you multiply two negative numbers you get a positive result.” – This, of course, is the exact opposite of what was asked, but it’s the given response.

## Why can’t polynomials have negative exponents?

A polynomial cannot have a variable in the denominator or a negative exponent, since monomials must have only whole number exponents. Polynomials are generally written so that the powers of one variable are in descending order.
