Question

Answer 1

a) 4¹⁰ . 8¹⁵ = (2²)¹⁰ . (2³)¹⁵ = 2²⁰ . 2⁴⁵ = 2⁶⁵

b) 4¹⁵ . 5³⁰ = 4¹⁵ . (5²)¹⁵ = 4¹⁵ . 25¹⁵ = (4.25)¹⁵ = 100¹⁵

c) 27¹⁶ : 9¹⁰ = (3³)¹⁶ : (3²)¹⁰ = 3⁴⁸ : 3²⁰ = 3²⁸

d) (3¹⁰ . 11 + 3¹⁰ . 5) : 3⁹ . 2⁴

= 3¹⁰ . (11 + 5) : 3⁹ . 2⁴

= 3 . 16 . 2⁴

= 3 . 2⁴ . 2⁴

= 3 . 2⁸

Answer 2

`a, 4^10 . 8^15`

`= 2^20 . 2^45`

`= 2^65`

`b, 4^15 . 5^30`

`= 2^30 . 5^30`

`= 10^30`

`c, 27^16 : 9^10`

`= 3^48 : 3^20`

`= 3^28`

`d, (3^10 . 11 + 3^10 . 5) : 3^9 . 2^4`

`= 3^10 . 2^4 : 3^9 : 2^4`

`= 3`
