Evaluate $\frac{8-[5-(-3+2)]+2}{|5-3|-|5-8|+3}$

On simplification of $\frac{(2.644)^{2}-(2.356)^{2}}{0.288},$ we get

The least number that must be subtracted from $63520$ to make the result a perfect square is

$(2 + \frac{3}{x}) \times (y + \frac{1}{2}) = \frac{31}{4}$,find the values of $x$ and $y$ if $x$ and $y$ are positive integers.

The value of $\frac{1}{2+\frac{1}{2+\frac{1}{2-\frac{1}{2}}}}$ is

The value of $\frac{(0.67 \times 0.67 \times 0.67)-(0.33 \times 0.33 \times 0.33)}{(0.67 \times 0.67)+(0.67 \times 0.33)+(0.33 \times 0.33)}$ is:
