Answer 1

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

Answer 2

Answer:

See below

Step-by-step explanation:

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

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

Hence, we are back starting with the original number
