was that (36^1/2 * xy^-2) all over (1000^-1/3*x^-3) then
= (36^1/2 * xy^-2) / (1000^-1/3 * x^-3)
= (36^1/2 * x * 1000^1/3 * x^3) / y^2
this is to make all the negative exponents positive
36^1/2 is the same as square root of 36 and 1000^1/3 is the same as cube root of 1000
so...
= (√36 * x * ∛1000 * x³ ) / y²
= (6 * x * 10 * x³) / y²
= (60 x^4) / y²
hope this helps.
