Question

CAN SOMEONE PLEASE ANSWER!

Answer 1

The first one

simplify the inside of the square root by dividing both 72 and 50 by 2 and subtracting 36 - 16 in the exponents of x

=
`\sqrt{}(36)/(25)` × 1/
`x^(20)`

=
`(6)/(5)` × 1 /
`x^(10)` = 6 / 5
`x^(10)`

Answer 2

`(6)/(5x^2)`

Explanation:

`\sqrt{}(72x^1^6)/(50x^3^6)`

Dividing the numerator and denominator by 2 gives;

`\sqrt{}(36x^1^6)/(25x^3^6)`

`√(36x^1^6)` =
`6x^(4)`

`√(25x^3^6)` =
`5x^(6)`

`(6x^4)/(5x^6)` =
`(6)/(5)` ×
`x^(4 - 6)`

This gives
`(6)/(5)` ×
`x^(-2)`

Which can also be written as
`(6)/(5x^2)`
