Question

7/5√3-5√2 denominator will be

Answer 1

Answer:

$\frac{7}{ 5\sqrt{3} - 5 \sqrt{2} } \times \frac{5 \sqrt{3} + 5 \sqrt{2} }{5 \sqrt{3} + 5 \sqrt{2} } \\ \frac{7(5 \sqrt{3} + 5 \sqrt{2} )}{(5 \sqrt{3} ) {}^{2} - (5 \sqrt{2}) { }^{2} } \\ \frac{35 \sqrt{3} + 35 \sqrt{2} }{25 \times 3 - 25 \times 2 } \\ \frac{35 \sqrt{3} + 35 \sqrt{2} }{75 - 50} \\ \frac{35( \sqrt{3} + \sqrt{2}) }{25} \\ \frac{7( \sqrt{3} + \sqrt{2} )}{5}$

using rationalization merhod we will find the denominator
