Multiply the fraction by![\frac{ \sqrt{2} + \sqrt{5} }{ \sqrt{2} + \sqrt{5} }](/tpl/images/2644/6310/b921d.png)
To multiply the fractions, multiply the numerators and denominators separately
Write the repeated multiplication in exponential form
Use (a-b)(a+b)=a²-b² to Simplify the denominator
Use (a+b)²=a²+2ab+b² to expand the numerator
Calculate the difference in denominator
Add the numbers in numerator
