Question

Compute \(\int_2^6\)7e^x dx.

(a) 30.82

(b) 7(e^6 – e^2)

(c) 11.23

(d) 81(e^6 – e^3)

This question was addressed to me during an internship interview.

I need to ask this question from Properties of Definite Integrals in chapter Integrals of Mathematics – Class 12

Answer 1

Right choice is (b) 7(e^6 – e^2)

Explanation: \(\int_2^6\)7e^x dx = 7(e^x)^62 dx

= 7(e^6 – e^2)
