As we have learnt,

 

Properties of Definite Integration -

If f(x)\geqslant g(x) for

all x\in \left [ a,b \right ] then

\int_{a}^{b}f\left ( x \right )dx\geqslant \int_{a}^{b}g(x)dx

-

 

 Since for x > 1,

x , x^2 < x^3 < x^4

 


Option 1)

\int_{1}^{b}x^{2}dx

Option 2)

\int_{1}^{b}x^{3}dx

Option 3)

\int_{1}^{b}x^{4}dx

Option 4)

\int_{1}^{b}xdx
