Answer : A
Explanation
Let 6250/√x= 625. Then √x= 6250/625 = 10 ⇒ 100
Answer : C
Explanation
√288/√128 =√(288/128) = √(144/64) = √144/√64 =12/8 =3/2
Q 3 - given that √3= 1.732, the value of 3 +√6 /(5√3-2√12 -√32+√50)is:
Answer : D
Explanation
Given exp = 3+√6/(5√3-2√4*3-√16*2+ √25*2) = 3+√6/(5√3-4√3-4√2+5√2) = (3+√6)/( √3+√2)*( √3-√2)/( √3-√2) = 3√3-3√2+√18-√12/(3-2) =(3√3-3√2+√9*2 -√4*3 )= (3√3-3√2+3√2-2√3) =√3= 1.732
Answer : C
Explanation
√36.1/102.4 = √361/1024 = √361/ √1024 =19/32
Answer : C
Explanation
given Expression = √441/1000000 = 21/1000 =0.021
Answer : B
Explanation
√ 0.00004761 = √4761/100000000 =69/10000= 0.0069
Q 7 - if √4096=64 , then the value of (√40.96 + √ 0.4096 + √0.004096 + √ 0.00004096) up to two places of decimal is :
Answer : C
Explanation
Given exp . √ 4096/100 +√ 4096/10000+√ 4096/1000000+√ 4096/100000000 =(64/10+ 64/100+64/1000+64/10000)= (6.4+0.64+0.064+0.0064+0.0064)= 7.11
Q 8 - if (5+ 2√3)/(7+ 4 √ 3) = a+b√3 , then
Answer : C
Explanation
a+b√3 = (5+2√3/ 7+4√3* 7-4√3/7-4√3) = (35-20√3+14√3-24)/(49-48) = 11-6√3
Answer : A
Explanation
7/(3+√2)= 7/(3+√2)*(3-√2)/(3-√2) =7*(3-√2)/(9-2)=(3-√2) = (3-1.414)=1.58
Answer : C
Explanation
√0.16/0.40 = √16/40 = √2/√5*√5*√5 = √10/5 =3.162/5 =0.632
