Solution by Steps
step 1
To find the definite integral of x4 x^4 from x=3 x = 3 to x=5 x = 5 , we use the fundamental theorem of calculus
step 2
The antiderivative of x4 x^4 is x55 \frac{x^5}{5} plus a constant
step 3
We evaluate x55 \frac{x^5}{5} at the upper limit of integration x=5 x = 5 and at the lower limit x=3 x = 3
step 4
The definite integral is [555][355] \left[\frac{5^5}{5}\right] - \left[\frac{3^5}{5}\right]
step 5
Simplifying, we get 312552435 \frac{3125}{5} - \frac{243}{5}
step 6
The result is 28825 \frac{2882}{5} , which can also be written as 576.4
Answer
The definite integral of x4 x^4 from x=3 x = 3 to x=5 x = 5 is 28825 \frac{2882}{5} or 576.4.
Key Concept
Definite Integral of a Polynomial Function
Explanation
The definite integral of a polynomial function xn x^n from a a to b b is found by evaluating the antiderivative xn+1n+1 \frac{x^{n+1}}{n+1} at b b and a a and then subtracting the two results.
