Simplify the expression.

Question

Simplify the expression.

(1/z)^9

I got 1/z^9 <--(The exponent is by the z only)

Answer 1

I think it would be z^-9

Answer 2

z^-9 is the same as 1/z^9

both answers are correct

Answer 3

To simplify the expression (1/z)^9, you can use the rule of exponents that states "when a fraction is raised to a power, you raise both the numerator and the denominator to that power."

Applying this rule to the given expression, we have:

(1/z)^9 = 1^9 / z^9

Since any number raised to the power of 1 is equal to the number itself, we can simplify further to:

1 / z^9

So your simplification is correct. The expression can be simplified to 1/z^9, where the exponent is by z only.
