Represent $\sqrt{8.2}$ on the number line.
Insert a rational number and an irrational number between the following:
$\frac{1}{3}$ and $\frac{1}{2}$
Express $0 . \overline{27}$ in the $\frac{p}{q}$ form.
If $\sqrt{5}=2.236,$ then evaluate $\frac{4-\sqrt{5}}{\sqrt{5}}$ correct to four decimal places.
Represent geometrically numbers on the number line:
$\sqrt{4.5}$
prove that.
$\left(1^{3}+2^{3}+3^{3}+4^{3}+5^{3}\right)^{\frac{1}{2}}$ $=\left(1^{3}+2^{3}+3^{3}+4^{3}\right)^{\frac{1}{2}}+\left(5^{3}\right)^{\frac{1}{3}}$
