Best ResponseYou've already chosen the best response.2Your goal is to make the same base so you can evaluate their powers.

Best ResponseYou've already chosen the best response.232 = 2 * 2 * 2 * 2 * 2 4 = 2 * 2 Theres an exponent rule that states having the same base allows for you to evaluate powers. \[\large a^x = a^y \implies x=y\]

Best ResponseYou've already chosen the best response.0@mthompson440 I kind of get it. I mean it's half of 32, but it was just confusing it's it's the exponent, not like multiplication.

Best ResponseYou've already chosen the best response.2\[4x=\frac{5}{2} \implies x = \frac{5}{2\cdot 4} = \frac{5}{8} \ne 1\]

Best ResponseYou've already chosen the best response.2\[32^{1/2} =\sqrt{32} = \sqrt{16 \cdot 2} = \sqrt{4^2 \cdot 2} = 4\sqrt{2} \ne 16\]
