Question

Rationalize the denominator of the following 1)1/✓7-2,2)1/✓5+✓2​

Answer 1

Answer:

1)(√7+1)/3

2)(√5-√2)/3

Step-by-step explanation:

1)

given 1/✓7-2  

denominator is √7 - 2 so, multiply and divide the equation with √7+2

= (1/✓7-2)*(√7+1)/(√7+1) = (√7+1)/(7-4) = (√7+1)/3

2)

given 1/(√5+√2)

denominator is √5+√2 so, multiply and divide the equation with  √5-√2

= (1/(√5+√2))*(√5-√2)/(√5-√2) = (√5-√2)/(5-2) = (√5-√2)/3
