Question

1. Which expression is equal to 4^0x4²?
A. 0
B. 1
C. 16
D. 64

Answer 1

The expression 4^0x4² can be simplified using the exponent rules which state that any number raised to the power of 0 equals 1. Therefore, we have:

4^0x4² = 1 x 4² = 16

So, the expression is equal to 16, which is option C.

Answer 2

• Concept: Exponents

• Solution:

You want to simplify the expression 4⁰×4².

We will use basic exponent properties for this.

First bear in mind that anything to the power of 0 is 1.

So that means that 4⁰ = 1.

We're not done yet because we still need to simplify the other part:

4².

Don't forget that:

4² ≠ 4×2

Because

4² = 4×4 which is 16

So we have 1 times 16 or just 16.

Answer: choice "c": 16
