L.H.S. = (1/5)^m x (1/2)^36daretodream wrote:(1/5)^m x (1/4)^18 = 1/(2(10)^35
solve for m, m=?
R.H.S. = (1/2)^36 x (1/5)^m
Hence,m=35.
It takes time and effort to explain, so if my comment helped you please press Thanks button

(1/5)^m x (1/4)^18 = 1/(2(10)^35daretodream wrote:(1/5)^m x (1/4)^18 = 1/(2(10)^35
solve for m, m=?
1/(5^m*4^18) = 1/(2(10)^35)
1/(5^m*2^36) = 1/(2(10)^35)
1/(5^m*2^36) = 1/2(5*2)^35
1/(5^m*2^36) = 1/2(5^35*2^35)
1/(5^m*2^36) = 1/(5^35*2^36)
m =35

Again its a similar problem....just make the base commondaretodream wrote:(1/5)^m x (1/4)^18 = 1/(2(10)^35
solve for m, m=?
(1/5)^m x (1/4)^18 = 1/(2(10)^35)
---> (1/5)^m x (1/2)^36 = 1/(2(2x5)^35)
--> (1/5)^m x (1/2)^36 = 1/(2^36 x 5^35)
[spoiler]Ans m= 35[/spoiler]

2*(10^35)=2*2^35 * 5^35=2^36*5^35daretodream wrote:(1/5)^m x (1/4)^18 = 1/(2(10)^35
solve for m, m=?
now lhs=5^m *4^18=5^m*2^36
equating RHS and LHS
m=35
