Answer:

He is right it is -500

Step-by-step explanation:

Answer 2

Answer:

-500

Step-by-step explanation:

(2a^4)^2

-----------------

a^0 a^5

We know ( xy) ^z = x^z y^z

so

(2a^4)^2 = 2^2 a^4^2

and x^y^z =x^(y*z)  so a^4^2 = a^(4*2) = a^8

(2a^4)^2 = 4 a^8

We know that a^0 = 1

4 a^8

-----------------

1 a^5

We know x^y / x^z = x^ ( y-z)

4 a^( 8-5)

4 a^3

Let a = -5

4 ( -5) ^3

4 ( -125)

-500
