Question

its urgent please help​

Answer 1

Answers calculation is below
a = 10 and b = 0

Answer 2

√5+√2/√5-√2=(√5+√2)(√5+√2)/(√5-√2)(√5+√2)=(√5)^2+(√2)^2+2(√5)(√2)/(√5)^2-(√2)^2=7+2√10

like this rationalizing √5-√2/√5+√2 we get 7-2√10.

7+2√10/3 +(7-2√10/3)=a+b√10

by adding we get

(7+7+2√10-2√10)/3=a+b√10

14/3=a+b√10

thus a=14/3

and b=0.

is this help the hit a love.
