- Homework Statement
- Simplify the expression:
##\sqrt{84 \,(y - 2)^ 3\; }##
- Relevant Equations
- None.
So I simplify the expression and get 2 x 3^2 x 7 = 84 and get ##2 \sqrt{21(y−2)^{3/2}}##
I don't follow how the answer is ##2(y -2) \sqrt{21 ( y - 2) }##
I don't follow how the answer is ##2(y -2) \sqrt{21 ( y - 2) }##
