The expression on the right hand side is a little bit confusing, both 10 and 35 are in the denominator? Can you please check again?santoshs wrote:1) If (1/5)m(1/4)18 = 1/2(10)35, m?

The question is :santoshs wrote:1) If (1/5)m(1/4)18 = 1/2(10)35, m?
(1/5)^m * (1/4)^18 = 1/(2(10)^35)
=> 5*(-m)=2^(36)/2*10^35 = 1/5^(35) = 5^(-35)
=> m = 35.
Thanks

If question is this... (1/5)^m * (1/4)^18 = 1/(2(10)^35)
we can write it as -> (1/5)^m * (1/2)^36 = 1/[2* (2*5)^35]
-> (1/5)^m * (1/2)^36 = 1/(2^36 * 5^35) -> [spoiler]m = 35 Ans.[/spoiler]
