Question

What is the third root of -216?

Answer 1

What number...times itself 3 times = -216?

hint *

-5^3 = -5 * -5 * -5 = -125
-7^3 = -7 * -7 * -7 = -343

so you answer is somewhere between there...can you figure out what it is?

Answer 2

do you know how to write the third root as an exponent, for example, the sqrt(4) = 4^(1/2)

Answer 3

7 @johnweldon1993

Answer 4

7*7 = 49
49*7 = something other than 216

Answer 5

I AM SO NOT GOOD AT THESE @whpalmer4

Answer 6

well, 7 is too big: 7*7*7 = 49*7 = 280+63=343
how about 5? 5*5*5 = 25*5 = 125, too small
how about 6? 6*6*6 = 36*6 = 180+36=216 Eureka!

Answer 7

and we need it to equal -216, so -6*-6*-6 = 36*-6 = -216
