This is my first time posting so I hope I am doing this right. I have an exponent problem that I can't figure out. Can someone help me?

This is my first time posting a question so I hope I am doing this right. I cannot solve this problem.

The question is:

If (1/5)^m*(1/4)^18=1/2(10)^35, what is m?

The answer choices are:

A) 17
B) 18
c) 34
d) 35
e) 36

Please search the question before starting a new thread ..
5^m *4^18 = 2*10^35
5^m * 2^36 = 2*2^35*5^35
5^m*2^36 = 2^36*5^35

thus m = 35 ..

do let me know if u have any doubts
