Question

Which expression is correctly simplified using the laws of exponents?

a. (a^0 b^3) = b^12

b. (a^4 b^2)^3 = a^7 b^5

c. (a^2) ^-3 = (a^9)
over over
(b^3) ( b^6)

d. (a^5) (a^3)
over = over
(b^3) b

Answer 1

A is the correct answer. i took the test.

Answer 2

I think the correct answer from the choices listed above is option B. The expression that is simplified using the laws of exponents correctly would (a^4 b^2)^3 = a^7 b^5. The rule that was followed was that that (x^m)(x^n) = x^(m+n). Hope this answers the question. Have a nice day.
