Select the three expressions that are equivalent to 6².
Choose 3 answers:
A (6^9/6^8)^2
B 6•6•6•6•6•6/6•6•6
C6^4/6^2
D2•2•2•2•2•2
E 6^5•6^7/6^10

Answer 1

A) C) E)

Explanation:

A (6^9 / 6^8)^2 = (6^(9-8)) ^2 = (6^1) ^2 = 6^2

B 6. 6. 6. 6. 6. 6 / 6. 6. 6 = 6^6 / 6^3 = 6^(6-3) = 6^3

C 6^4 / 6^2 = 6^(4-2) = 6^2

D 2.2.2.2.2.2 = 2^6 = 64

E 6^5 . 6^7 / 6^10 = 6^(5+7) /6^10 = 6 ^ 12 / 6 ^10 = 6^(12-10) = 6^2

Therefore, A, C, E = 6^2
