Question

How do you simplify `\frac { 72x ^ { \frac { 3} { 4} } } { 9x ^ { \frac { 1} { 2} } }`?

Answer 1

`8x^(1/4)`

Explanation:

This is the same as: `ubrace((72-:9))xxubrace((x^(3/4)-:x^(2/4)))`

`color(white)("dddddddddddddddddd")8color(white)("dd")xx color(white)("ddd")x^(3/4-2/4)`

`color(white)("ddddddddddddddddddddd")8x^(1/4)`
