Question

simplify:(64/125)^-2/3+(625/256)^1/4+25/3√64.

Answer 1

(64/125)^(-2/3) + (625/256)^1/4 + 25/3Root64
We know that,
64 = 4^3
125 = 5^3
625= 5^4
256 = 4^4
root 64 = 8
Substitute these values:
(4^3/5^3)(-2/3) + (5^4/4^4)^1/4 + 25/3*8
(4/5)^(-2) + (5/4) + 25/24
(5/4)^2 + 5/4 + 25/24
25/16 + 5/4 + 25/24
5/4* [ 5/4 + 1 + 5/6] =  5/4*[15+12+10/12]
= 5/4 * 37/12 = 185/48 = 3.85 (approx)
