If \((\frac{1}{5})^m * (\frac{1}{4})^{18} = \frac{1}{2*(10)^{35}}\), then m = ?
A. 17
B. 18
C. 34
D. 35
E. 36
Exponent property #1: \((\frac{a}{b})^k=\frac{a^k}{b^k}\)
Exponent property #2: \((b^x)^y = b^{xy}\)
Exponent property #3: \((ab)^x = a^xb^x\)

Given:\((\frac{1}{5})^m * (\frac{1}{4})^{18} = \frac{1}{2*(10)^{35}}\)
Applying exponent property#1, we get: Given:\( (\frac{1^m}{5^m})(\frac{1^{18}}{4^{18}} ) =\frac{1}{2*(10)^{35}} \)
