Question

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

Answer 1

Answer:

(5\sqrt{3} +5\sqrt{2} )(5

3

+5

2

) Answer:

Denominator after rationalizing is 25

Step-by-step explanation:

AS YOU CAN WE HAVE TO RATIONALIZE

SO MULTIPLY WITH

CONJUGATE AND DIVIDE WITH THE SAME NUMBER

HERE THE CONJUGATE IS

5\sqrt{3} +5\sqrt{2}5

3

+5

2

SO AFTER MULTIPLYING AND DIVIDING WE GET

(5\sqrt{3} )^{2} -(5\sqrt{2})^{2}(5

3

)

2

−(5

2

)

2

WHICH IS ALSO EQUAL TO

5X5X3-5X5X2

75-50

25
