Answer:


x=3/2=1.5

Explanation:

So we have the equation:


49=7^(2x-1)

Note that 49 is the same as 7 squared. Thus:


(7)^2=(7)^(2x-1)

Since they now have the same base, the exponents must be equal to each other. So:


2=2x-1

Add 1 to both sides:


3=2x

Divide both sides by 2:


x=3/2=1.5

And we're done!
