Question

4¹⁰×8¹⁵=

Answer 1

4¹⁰ x 8¹⁵

= ( 2² ) ¹⁰ x ( 2³ ) ¹⁵

= 2^2.10 x 2^3.15

= 2²⁰ x 2⁴⁵

= 2^{20 + 45}

= 2⁶⁵

Answer 2

\(=\left(2^2\right)^{10}.\left(2^3\right)^{15}=2^{20}.2^{45}=2^{65}\)

Answer 3

4¹⁰ . 8¹⁵ = (2²)¹⁰  . (2³)¹⁵ = 2¹⁰ . 2⁴⁵ = 2¹⁰⁺⁴⁵ = 2⁵⁵

Answer 4

Nhầm

= 2²⁰ . 2⁴⁵ = 2²⁰⁺⁴⁵ = 2⁶⁵
