We'll use PEMDAS which stands for
P = parenthesis
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
It tells us the order in how to evaluate math expressions. We start with parenthesis, then move to exponents, etc until we get to subtraction as the last step.
We have parenthesis so we focus on whats inside it. We evaluate 2^0 to get 1. Any nonzero number to the exponent 0 is always 1. In other words, x^0 = 1 where x is nonzero.
So 3(2^0) turns into 3(1) or 3*1
Then we multiply that to get 3*1 = 3
So overall, 3(2^0) = 3
Can we get a picture please
Answer:
A
Step-by-step explanation:
A is not a polynomial as the power of x is less than one
The point-slope form:

- slope
- point
We have the point
and the slope 
Substitute:

It means to convert 3liters to mL
400g to kg
And so as the following
