PROBLEM
∫12x51dx
STEP 1
1. The integral ∫12x51dx is a definite integral.
2. We will use the power rule for integration to solve this integral.
STEP 2
1. Rewrite the integrand in a simpler form.
2. Apply the power rule for integration.
3. Evaluate the antiderivative at the bounds.
4. Calculate the definite integral.
STEP 3
Rewrite the integrand x51 in a simpler form using negative exponents:
x51=x−5
STEP 4
Apply the power rule for integration, which states that ∫xndx=n+1xn+1+C, where n=−1:
∫x−5dx=−5+1x−5+1+C=−4x−4+C=−41x−4+C
STEP 5
Evaluate the antiderivative −41x−4 at the bounds 1 and 2:
[−41x−4]12=(−41(2)−4)−(−41(1)−4)
STEP 6
Calculate the values:
−41(2)−4=−41⋅161=−641 −41(1)−4=−41⋅1=−41
SOLUTION
Subtract the evaluated values to find the definite integral:
−641−(−41)=−641+41 Convert 41 to a fraction with a denominator of 64:
41=6416 Now perform the subtraction:
−641+6416=6415 The value of the definite integral is:
6415
