Answer:
•3² × 3⁴ ×3⁸
= 3²+⁴+⁸
= 3¹⁴
•(5²)³ ÷ 5²
= 5²×³ ÷ 5²
= 5⁶÷5²
= 5⁶-²
= 5⁴
•(2²⁰÷2¹⁵)×2³
= (2²⁰-¹⁵) × 2³
= 2⁵ × 2³
= 2⁵+³
= 2⁸
•25⁴÷5³
= (5²)⁴ ÷ 5³
= 5²×⁴ ÷ 5³
= 5²+⁴ ÷ 5³
= 5⁶ ÷ 5³
= 5⁶-³
= 5³

1. 3²×3⁴×3⁸=3²+⁴+⁸
=3¹⁴
2. (5²)³÷5³=((5)²×³)÷5³
=5⁶÷5³
=5⁶-³ =5³
3. (2²⁰÷2¹⁵)×2³=(2²⁰-¹⁵)×2³
=2⁵×2³ =2⁵+³
=2⁸
4. 25⁴÷5³
First we have to convert 25 into the power of 5
=(5²)⁴÷5³
=(5²×⁴)÷5³
=5⁸÷5³
=5⁸-³
=5⁵
These are the answers, hope they help!!
