(1/5)^m *(1/4) ^18 = (1/2) * (1/10) ^35

(1/5)^m * ((1/2) ^2)18) = (1/2) * (1/10) ^35

(1/5)^m * (1/2) ^36 = (1/2) * ((1/2)* (1/5)) ^ 35

(1/5)^m * (1/2) ^36 = (1/2) * (1/2) ^ 35 * (1/5) ^ 35

(1/5)^m * (1/2) ^36 = (1/2) ^ 36 * (1/5) ^35

(1/5)^m = (1/5) ^35

m = 35

Enjoy!!!!

(1/5)^m*(1/4)^18=1/2(10)^35

if m = 35

(1/5)^35*(1/2^36)
=(1/5^35)*(1/2^36)
= 1/5^35*2^35*2
= 1/(5*2)^35 * 2
= 1/2(10)^35
