Question

I have a math question, and i will upload the picture as soon as the session starts.

Answer 1

We have to solve this expression with positive exponents:

`\begin{gathered} 7^{(1)/(2)}\cdot7^{-(2)/(3)} \\ 7^{(1)/(2)-(2)/(3)} \\ 7^{(1\cdot3-2\cdot2)/(2\cdot3)} \\ 7^{(3-4)/(6)} \\ 7^{-(1)/(6)} \\ \frac{1}{7^{(1)/(6)}} \end{gathered}`

Answer: 1/7^(1/6)

`\frac{1}{7^{(1)/(6)}}`
