42.51 is the right answer
Answer:
40x/(15x²y²)
Step-by-step explanation:
8/(3xy²) Multiply by 5/5
= 40/(15xy²) Multiply by x/x
= 40x/(15x²y²)
Answer:
1.14200738982×10^26
Step-by-step explanation:
Substitution can make this integral much easier to evaluate.
<h3>Substitution</h3>
Let u = 7x² -x. Then du = (14x -1)dx. The limits on x become different limits for u:
for x = 1: u = 7(1²) -1 = 6
for x = 3: u = 7(3²) -3 = 60
