Simplify. Remember to use absoulute value notattion when necessary. If a root cannot be simplified state this.
{(7b)exponent4}^(1/4) I did something wrong when I did it.

[(7b)^4]^(1/4) = (7b)^(4 * 1/4) = (7b)^1 = 7b
You know, if you try to solve a problem, get it wrong, and decide to ask for help, it might be useful if you show what you did, so we can pinpoint the error.
Of course, when you view the solution, I guess you'll figure that out . . .
