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

answers are:

17
18
34
35
36


(1/5)^m * (1/4)^18 = 1/2 * 1/(5*2)^35
= 1/2 * (1/2)^35 * (1/5)^35
(1/5)^m * (1/2)^36 = (1/2)^36 * (1/5)^35
Hence m =35
What is the OA?

3^x - 3^x-1 = 162

3^x(1-3^-1) = 162

3^x(1-1/3) = 162 ==> 3^x* 2/3 = 162

3^x/3 = 81

3^(x-1) = 3^4

(x-1) = 4

x = 5 ===> x(x-1) = 5 * 4 = 20
