equations with square roots and cube roots

Answer 1

The answer is : 4/7
Decimal: 0.571 (Not Rounded)

Answer 2

See below

Explanation:

If you are squaring a number, and then taking the square root of it, you are essentially undoing the original operation:

`\displaystyle \sqrt{\biggr((4)/(7)\biggr)^2}=\biggr[\biggr((4)/(7)\biggr)^2\biggr]^{(1)/(2)}=\biggr((4)/(7)\biggr)^{2*(1)/(2)}=(4)/(7)`

Hence, we are back starting with the original number
