For Problems 2–4, calculate the integral, and circle your final answer. Show enough steps so that it's clear that you, and not a calculator, calculated the integrals. In particular, to receive full credit, all of the following steps must be shown: choose your u, calculate your du and solve for dx, show the algebraic details of how you rewrote your integral in terms of u, and then calculate the integral. x7 dx x8 + 5 2. 3. e cos(1 + 3e") dx re3 dx 4.

Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
