Answer:
1) ∫ x² e^(x) dx
4) ∫ x cos(x) dx
Step-by-step explanation:
To solve this problem, eliminate the choices that can be solved by substitution.
In the second problem, we can say u = x², and du = 2x dx.
∫ x cos(x²) dx = ∫ ½ cos(u) du
In the third problem, we can say u = x², and du = 2x dx.
∫ x e^(x²) dx = ∫ ½ e^(u) du
3cd^2(6cd + 14cd^2)
18cd^3 + 42cd^4
Yes because simplified 9/15 equals 3/5 and 6/10 also equals 3/5
Answer:
The simplify form of the provided expression is:
Step-by-step explanation:
Consider the provided expression.

Now simplify the above expression as shown below:

as 16/8 = 2
Now again simplify the above expression.
as 2/6 = 1/3
Now, multiply the whole expression with 3.
Hence, the simplify form of the provided expression is:
