(4x/y^3)^-3 **Weegy:** solve for one variable at a time. start with y.
(4x/y3)-3=0
+3 +3
(4x/y3)=3
now multiply both sides by 1/4x to cancel the 4x on the top. [ like this:
(4x/3y) * 1/4x= 3/4x
3y=(3/4x)
/3 /3
y=(3/4x)/3
now take this and plug it back into the original problem for the y value to get your x. like this:
[(4x) / {(3/4x)/3} * 3] -3.
now solve that to get your x. then take your x value from that and plug it in to the original again to get your actual y value.
its a long process but kinda straightforward. hope this helps. sorry i could finish it all the way. running out of battery.

The answer for (4x/y^3)^-3 is 1/64x^3.

(4x/y^3)^-3

=4^-3x^-3/1

=1/64x^3 /1

=1/64x^3

(4x/y^3)^-3

=4^-3x^-3/1

=1/64x^3 /1

=1/64x^3

evaluate or simplify the numerical expression: (16)^1/2 **Weegy:** When multiplying the same number but with exponents, you add the exponents.
So you're going to get 3+1/2 = 7/2
which is 11^7/2 or 1331(11^1/2)
simplified = 4,414.42759 (More)
