Transcript text: Evaluate the definite integral
\[
\int_{8}^{8}\left(9 x^{10}+1\right)^{6 / 2} d x
\]
Solution
Solution Steps
Step 1: Analyze the Integral
The integral to evaluate is:
\[
\int_{8}^{8}\left(9 x^{10}+1\right)^{6 / 2} \, dx
\]
Notice that the lower and upper limits of integration are the same (both are 8). This means the integral is evaluated over a single point.
Step 2: Simplify the Integrand
Simplify the integrand:
\[
\left(9 x^{10} + 1\right)^{6 / 2} = \left(9 x^{10} + 1\right)^3
\]
However, this simplification is not necessary for solving the problem, as the integral is over a single point.
Step 3: Evaluate the Integral
When the lower and upper limits of integration are the same, the definite integral evaluates to 0. This is because the integral represents the area under the curve, and over a single point, the area is 0.
