# Zero Exponent

How to solve the zero exponent a^{0}: formula, 2 examples, and their solutions.

## Formula

### Formula

a^{0} = 1

(a ≠ 0)

If the exponent is 0, then that value is 1.

## Example 1

### Example

### Solution

The exponent of 2^{0} is 1.

And the base, 2, is not 0.

So 2^{0} = 1.

## Example 2

### Example

### Solution

The base of y^{0} is 0.

And y ≠ 0.

So y^{0} = 1.

The base of (-3xy)^{0} is 0.

And -3xy ≠ 0.

So (-3xy)^{0} = 1.

So the given expression is (4x^{2}⋅1)⋅1.

(4x^{2}⋅1)⋅1 = 4x^{2}

So 4x^{2} is the answer.
