What is the answer to 13, 14, and 15?

Answer 1

Explanation:

13.

`\implies\sf{ {x}^(2) = 144 } \\ \\ \implies\sf{ x = \pm √(144) } \\ \\ \implies\sf{ x = \pm 12 }`

14.

`\implies\sf{ {x}^(2) = (25)/(289) } \\ \\ \implies\sf{ x = \pm \sqrt{ (25)/(289) } } \\ \\ \implies\sf{ x = \pm (5)/(17) }`

15.

`\implies\sf{ {x}^(3) = 216 } \\ \\ \implies\sf{ x = \sqrt[3]{216} } \\ \\ \implies\sf{ x = 6 }`
