## anonymous 5 years ago Evaluate: -32^0.8 what would the 0.8 be in a radical?

1. anonymous

hmm i forgot but i think so you might wanna check but i think so fractional exponents would also be in a radical form also usually used in calc

$-32^{0.8}$ 0.8=4/5 $-32^{4/5}$ or $(-32^4)^{1/5}$ in radical from $\sqrt[5]{-32^4}$

3. ash2326

now 32=2^5 so $(-32)^{1/5}=-2$ we'll have now $-2^4$ which is -16

sorry it'd be +16
