Break this down by examining components.
4^3=64; 3^4=81; 2^3=8; 2^sqrt(36)=2^6=64.
Now, rewrite the expression:
((64+81)/(64-8))/(7*8/5)=145/56 * 5/56 (dividing by a fraction means multiplying by its inversion, interchanging numerator and denominator).
(145*5)/(56*56)=725/3136. What a pity ÷ hadn't been * instead, because the answer would have been simplified to 29, since 56 would have cancelled out and 5 would have divided into 145 to give 29.
