1.27272727....... can be expressed in p/q form as

Find the value of x, if $3^{\left(x-10\right)}=\ 27$  

Determine if the product of  $3\sqrt{2}$  and  $8\sqrt{18}$  is rational or irrational.

What would be the denominator after rationalizing 7/(5√3 - 5√2)?

The value of  $\sqrt{10}$  = 3.162, then the vale of  $\frac{1}{\sqrt{10}}$  is

 $Express\ 2.4\overline{178}$    as a fraction in simplest form.

 $Simplify\ \frac{4}{2+\sqrt{3}+\sqrt{7}}$    the by rationalizing the denominator:

 $Simplify\ :\ \frac{1}{(3-√8)}-\frac{1}{(√8-√7)}+\frac{1}{√7-√6)}-\frac{1}{(√6-√5)}+\frac{1}{(√5-2)}$  

 $Ifx=3+√8,thenfindthevalueof(i)x^2+1/x^2$  

 $If\ a\ and\ b\ are\ rational\ numbers\ and\ \frac{(√11-√7)}{(√(11)+√7)}=a-b√77,the\ values\ ofa\ and\ b\ are$
