Answer:
Step-by-step explanation:
<u>Solving exponents</u>
- a. 5^-2 = 1/5^2 = 1/25
- b. (3^2)^3/3^8 = 3^6/3^8 = 1/3^2 = 1/9
Answer with Step-by-step explanation:
For any complex number x+iy the polar form is represented as

where

Part a) x+iy = -1+i
Thus 
Thus using De-Morvier's theorem

Part 2) x+iy = 1+3i
Thus 
Thus using De-Morvier's theorem

3.162 and 3.162. (3.162 is the rounded square root of 10)
Answer:
g(-5) = -127
Step-by-step explanation:
Plug in -5 for x:
g(-5) = (-5)^3 - 2
= -125 - 2
= -127
Solution steps:
1. Add the two given fractions.
2. Subtract the sum from 10 to find your answer.
