If (5^4)m=5^12 What is the value of M
Scrat [10]

Answer:

Step-by-step explanation:

Easy way to solve

5^4 = 625.

5^12=244140625.

Thus, 625m=244140625.

Divide both sides by 625/

m=390625, or 5^8.

Better way to solve

When dividing by exponents x^{4}/x^{2} =x^{4-2}=x^2

Thus, simply do 12-4=8 to know that m=5^8.
