Question

What is the value of 9^-6/9^-4?

Answer 1

9^-2 or 1/81

Explanation:

Exponent Rule:

When dividing exponents, they're subtracted.

Since the second term has a negative exponent, we add.

Change the problem into multiplication, then add 4 to the exponent of -6:

`(9^(-6) )/(9^(-4) ) = 9^(-6) * 9^(4)=9^(-2)`
`or`
`(1)/(81)`
