Question

plz solve this plz do not report this plz.ok

Answer 1

we can write ,,

√10 = √5 x √2

now solving the numerator part first,,

√10-√5= (√5)(√2)- √5
taking √5 as common

√5(√2-1)


Now our fraction becomes
√5(√2-1)/2√2

Rationalising the denominator

{√5(√2-1)(√2)} / 2(√2)(√2)
√10(√2-1)/4
= (2.236)(1.414)(1.414-1)/4
= (2.236)(1.414)(0.414)/4

now 2.236/4= 0.559

={0.559}{1.414}{0.414}
= 0.327
