a) 2⁵×4¹³×8⁵⁰ = 2⁵×(2²)¹³×(2³)⁵⁰=2⁵×2²⁶×2¹⁵⁰=2¹⁸¹
b) 10⁶²: 100³⁰= 10⁶²:(10²)³⁰=10⁶²:10⁶⁰=10²=100
c) 3⁶ × 27²⁰ : 9³³ =3⁶ × (3³)²⁰ ÷ (3²)³³=3⁶ × 3⁶⁰ ÷ 3⁶⁶=3⁶⁶÷ 3⁶⁶=1
d) 27⁸⁶÷ 9⁴⁰ =(3³)⁸⁶÷ (3²)⁴⁰=3²⁵⁸÷3⁸⁰=3¹⁷⁸
e) 125¹⁴ × 5⁷: 5⁵ = (5³)¹⁴ × 5²=5⁴² × 5²=5⁴⁴
f) 27¹⁰ × 81² : 3³⁸ = (3³)¹⁰× (3⁴)²÷3³⁸=3³⁰× 3⁸÷3³⁸=3³⁸÷3³⁸=1
