1. Multiplying powers with same base
For example: x² × x³, 2³ × 2⁵, (-3)² × (-3)⁴
In multiplication of exponents if the bases are same then we need to add the exponents.
Dividing powers with the same base
For example:
3⁵ ÷ 3¹, 2² ÷ 2¹, 5(²) ÷ 5³
In division if the bases are same then we need to subtract the exponents.
3. Power of a power
For example: (2³)², (5²)⁶, (3² )−3
In power of a power you need multiply the powers.
