( 2 ^ 4 ) ^ 3 = ( 2 ^ 3 ) ^ 4 = 8 ^ 4
64 ^ 2 = ( 8 ^ 2 ) ^ 2 = 8 ^ 4
prove, using the law of exponents, that the following is true
(2^4)^3=(64)^2
(use the same bases to rewrite the expression)
the second half of =(8)^2 (8)^2
=(4)^2 (2)^2 (4)^2 (2)^2
=(2)^2(2^2)(2^2)(2^2)(2^2)(2^2)
now the first part
(2^4)^3
2x2x2x2
2x2x2x2
2x2x2x2
so put both sides together and get
2x2x2x2=2x2x2x2
2x2x2x2=2x2x2x2
2x2x2x2=2x2x2x2
Is this correct?
Thanks for checking my work

but the question said it the expression should have the same base, so wouldn't you have to go further?
changing to the same base
(2^4^3
= 2^12
64^2
= (2^6)^2 = 2^12
therefore (2^4)^3 = 64^2
(2^4^3
= 2^12
64^2
= (2^6)^2 = 2^12
therefore (2^4)^3 = 64^2
I thought having the same base meant having the same number if it can be in simplier form. that is why I made them all multiples of 2.
