In which expression should the exponents be multiplied?
2^9 over 2^7
(6^10) ^-7
(1/2)^3 • (1/2) ^5
5^2 • 5^4

Answer 1

Answer:

$(6^{10})^{-7}$

Step-by-step explanation:

Apply the power rule of exponents: $(a^m)^n=a^{m\times n}$.

From the given options, the only expression in this form is

$(6^{10})^{-7}$

When we apply the above rule, we get:

$(6^{10})^{-7}=6^{10\times -7}$

$(6^{10})^{-7}=6^{-70}$

All the other options are of the form: $a^m\times a^n=a^{m+n}$

The correct choice is the second option
