Any base to the power of 0 = ?

1
except 0

2² × 2³ 

2² × 2³ = 2^{2 + 3} = 2⁵

You can add exponents if you are multiplying powers with the same bases.

3⁵ ÷ 3²

3⁵ ÷ 3² = 3^{5 – 2} = 3³

You can subtract exponents if you are dividing powers with the same bases

(4²)³ 

(4²)³ = 4^{2 x 3} = 4⁶

You can multiply exponents if you are raising a power to a power with numbers of the same base.

2^-2

When you have a base with a negative exponent, you can make the exponent positive by moving the base to the opposite side of a fraction.
