Prove that `4 lt= int_1^3 sqrt(3+x^2) dx lt= 4sqrt(3)`

Text Solution

Verified by Experts

The correct Answer is:
NA
Since `1lexle3`
or `1lex^(2)le9`
or `4lex^(2)+3le12`
or `2lesqrt(3+x^(2))le2sqrt(3)`
or `2(3-1)leint_(1)^(3)sqrt(3+x^(2))dx le 2sqrt(3)(3-1)`
or `4le int_(1)^(3)sqrt(3+x^(2))le 4 sqrt(3)`
