Question

Simply. If the solution is not a real number enter not a real number rotate picture answer all 3 please

Answer 1

13.
`\frac{\sqrt[5]{x^4} }{x}`.

14.
`v = \pm3√(5)`

15. 2.

Explanation:

13.
`x^(1/5) * x^(-2/5)`

=
`x^(1/5 + (-2/5))`

=
`x^(1/5 - 2/5)`

=
`x^(-1/5)`

=
`(1)/(x^(1/5))`

=
`(x^(4/5))/(x^(1/5 + 4/5))`

=
`(x^(4/5))/(x)`

=
`\frac{\sqrt[5]{x^4} }{x}`.

14.
`v^2 - 45 = 0`

`v^2 = 45`

`√(v^2) = \pm√(45)`

`√(v^2) = \pm√(3^2 * 5)`

`v = \pm3√(5)`.

15.
`\sqrt[3]{2} * \sqrt[3]{4}`

=
`\sqrt[3]{2 * 4}`

=
`\sqrt[3]{2 * 2 * 2}`

=
`\sqrt[3]{2 ^3}`

= 2.

Hope this helps!
