$w^{-3} = \frac{1}{64}$ by laws of exponents, $a^{-b} = \frac{1}{a^b}$so we can write that as $\frac{1}{w^3} = \frac{1}{64}$ it should be clear that this means $w^3=64$What number $$w$$ makes $$w^3=w*w*w=64$$ a true statement?

@SwagHatKid What is it

15. whpalmer4

@DredayAJO Let's try some possible values for $$w$$: how about $$w = 2$$? $2*2*2 = 8$oops, that's too small how about $$w = 5$$? $5*5*5 = 125$oops, too big

:) thanx m8

@DredayAJO have you tried $$w = 3$$ and $$w = 4$$?

Can you help me with a direct answer or no?

@DredayAJO If you can't be bothered to try multiplying 3*3*3 and 4*4*4 and see if either of them give you the answer you need, you may just be stuck. The OpenStudy Code of Conduct says that we are to guide you to find the answer, not do it for you.
