Answer:
9.3
Step-by-step explanation:
(3/√5+√2) + (7/√5-√2)
on taking LCM we get
=3(√5-√2)+7(√5+√2)/(√5+√2)
(√5-√2)
=3(√5-√2)+7(√5+√2)/[(√5)^2]-[(√2)^2] [using identity : (a+b)(a-b) = a^2-b^2 in denominator]
=3(√5-√2)+7(√5+√2)/5-2
now putting values of √5=2.236 and √2=1.414 we get
=3(2.236-1.414)+7(2.236+1.414)/3
3*0.822+7*3.65/3
=2.466+25.55/3
=28.016/3
=9.338666•••••
=9.3(approx.)
