The expression (y^20) (y^-5)^2 is equivalent to y^n. What is the value of n? n = 27 n = 10 n = -200 n = 17

n = 10

Step-by-step explanation:

Using the rules of exponents

× ⇔

=

Given

( ) (

= ×

=

= → in the form with n = 10

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
