Question

I need help with number 3 ASAP

Answer 1

Hello!

To convert fraction exponents to radical form, use the formula:
`x^{(m)/(n) } = \sqrt[n]{x^(m) }`.

With that formula, we can convert 9^1/2 into a radical.

`9^{(1)/(2)` =
`\sqrt[2]{9^(1) }` = 3

With the fraction exponent converted and simplified, we can find the value of x.

`9^{(1)/(2) }` ×
`9^{(1)/(2) }` = 3 × 3 = 9

9 =
`\sqrt[x]{81}`

Using perfect squares, which are numbers multiplied by itself, the square root of 81 is 9, so therefore, x is equal to 2.

Final answer: Two
