Question

What is the following sum?
If these equation.

Answer 1

`7(\sqrt[ 5 ]{ { x }^( 2 ) y })`

Explanation:

The equation:

`4 \sqrt[ 5 ]{ { x }^( 2 ) y } +3 \sqrt[ 5 ]{ { x }^( 2 ) y }`

1) Collect like terms by adding their coefficients (
`3` and
`4`)

`(3+4)\sqrt[ 5 ]{ { x }^( 2 ) y }`

2) Calculate

`7(\sqrt[ 5 ]{ { x }^( 2 ) y })`

Answer 2

`4\left(\sqrt[5]{x^2 y} \right) +3 \left( \sqrt[5]{x^2 y} \right)\\\\=(4+3) \left( \sqrt[5]{x^2 y} \right)\\\\=7 \left( \sqrt[5]{x^2 y} \right)`
