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

Hello,

if have a hard time figuring out how to solve the equation for m. I thought about splitting it up somehow or getting the left side to have a common denominator but I still didn't get anywhere. It would be great if you could help me.

Thank you
