A: x = 0

B: x = All real numbers

Step-by-step explanation:

A.

Any number to the power of (0) equals one. This applies true for the given situation; one is given an expression which is as follows;

Simplifying that will result in;

As stated above, any number to the power of (0) equals (1), thus (x) must equal (0) for this equation to hold true.

B.

As stated in part (A), any number to the power (0) equals (1). Therefore, when given the following expression;

One can simplify that;

However, (1) to any degree still equals (1). Thus, (x) can be any value, and the equation will still hold true.

y=mx+b

step-by-step explanation:

m slope

b y-intercept

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
