Question

viết các tich sau dưới dạng lũy thừa

a: 8⁴x16⁵x32

b; 27⁴x81¹⁰

 

Answer 1

a)

\(8^4.16^5.32=2^{12}.2^{20}.2^5=2^{37}\)

b)

\(27^4.81^{10}=3^{12}.3^{40}=3^{52}\)

Answer 2

a ) 8⁴ . 16⁵ . 32 = ( 2³ ) ⁴ . ( 2⁴ ) ⁵ . 2⁵ = 2¹² . 2²⁰ . 2⁵ = 2^{12 + 20 + 5} = 2³⁷

b ) 27⁴ . 81¹⁰ = ( 3³ ) ⁴ . ( 3⁴ ) ¹⁰ = 3¹² . 3⁴⁰ = 3¹²⁺⁴⁰ = 3⁵²

Answer 3

a, \(8^4.16^5.32=\left(2^3\right)^4.\left(2^4\right)^5.2^5=2^{12}.2^{20}.2^5=2^{37}\)

b, \(27^4.81^{10}=\left(3^3\right)^4.\left(3^4\right)^{10}=3^{12}.3^{40}=3^{52}\)

Answer 4

a) 8⁴ . 16⁵ .32 = 2¹². 2²⁰ . 2⁵=2³⁷

b) 27⁴ . 81¹⁰ = 3¹² . 3⁴⁰ = 3⁵²
