Answers:
Part A.
2.) a. 35x
The only affected variable is the y variable, and there's a rule of exponents that states that whenever a number (that is not equal to 0) is raised to the power of 0, it is always equal to 1.
3.) d.
Same reason with question 1. The z variable is raised and is multiplied by 9y. There's no change at all since 9y is multiplied by 1.
4.) b. 1
No need to solve inside the parentheses. They're raised to the power of 0, so it's always equal to 1.
5.) a. 10
Proof:
Part B.
6.) b.
Proof:
7.) a.
6 raised to the power of negative 3. According to the properties of exponents, any expression raised to the power of a negative is equal to its reciprocal. For instance, .
8.) c.
Follow the rule of exponents (from number 7). But since t is not raised to the power of a negative number, there is no need for it to make it into a reciprocal.
9.) b.
16 and x are both raised to the power of negative 2. Make them into a reciprocal, and still raise them to the power of 2
( = = )
