Would the 7 become 49 in this equation?
5x^3(7x)^2
I have a test tomorrow and I was just wondering... would the ^2 distribute to the 7 and the X or just the X?
Thanks so much!

With parentheses around the 7x the squaring applies to both the 7 and the x.

Yes, you would. Both items in the parentheses are being squared.
(7x)² = 49x²
Similarly if you had additional variables inside the parentheses, they would be squared also:
(3abc)² = 9a²b²c²
P.S. The expression above would be simplified to:
245x^5
