D bc u are tryna to find x
Answer:
a. - 1 3/4
b. 6
Step-by-step explanation:
For each, plug in the given number to the corresponding variable:
a. When x = -2. Plug in -2 for x in the given expression:
2^(-2) - 2
Simplify. Note that when a negative sign is located in the power sign, you would do the normal power, and then put the number over 1.
2^(-2) = 1/(2 x 2) = 1/4
Simplify:
1/4 - 2 = - 1 3/4
- 1 3/4, or -7/4 is your answer.
b. When x = 3. Plug in 3 for x in the given expression:
2^(3) - 2
Simplify. First solve the power, then subtract:
2^3 = 2 * 2 * 2 = 4 * 2 = 8
8 - 2 = 6
6 is your answer.
