Question

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

Answer 1

Answer:

Step-by-step explanation:

7/(5√3 - 5√2)

rationalise the denominator

so,  7/(5√3 - 5√2) × (5√3 + 5√2)/ (5√3 + 5√2)

 7(5√3 + 5√2)/ 5√3]² -  [5√2]²              {by identity [a+b] [a-b] = a² -b²}

35√3 + 35√2/75-50

35√3 + 35 / 25

so the denominator is 25
