Question

Given: √3 = 1.732; √5=2.236
Then find the value of
1 / 4√3 - 3√5

Answer 1

Given: √3 = 1.732;
            √5=2.236
Then  the value of   1 / 4√3 - 3√5 will be-

4√3 = 4*1.732= 6.928  nearly 6.9
3√5  = 3*2.236= 6.708 nearly 6.7

now 1 / (4√3 - 3√5) then answer will be 1/(6.9-6.7) =1/0.2 = 5 Ans

Else if the question is- 

(1/4√3)-3√5 then the answer will be (0.14)- 6.7 =  -6.56
