Answer 2

Answer:

3²(3 power 2)

Step-by-step explanation:

(3power-7 ÷ 3power-10) × 3power-5

• As per rule a power -1 = 1/1/a power 1

•( 1÷1/3power7 ÷ 1÷1/3power 10)× 1÷1/3power 5

•(3/1power7 ÷ 3/1power10) × 3/1power 5

•As base is same and it's divison so changing of powers = a¹÷a² = a¹-²

•( 3power 7-10) × 3power5

• 3power-³×3power5

•Again now base is same but it's multiply so changing of powers = a¹×a² = a¹+²

• 3-³+5

• 3²

Therefore, answer = 3power²
