a 4^10.8^15=(2^2)10.(2^3)^15=2^20.2^45=2^65

b 4^15.5^30=(2^2)^15.5^30=2^30.5^30=10^30

c 27^16.9^10=(3^3)^16.(3^2)^10=3^48.3^20=3^68 ( nếu đúng thì tick nhé )

4^10*8^15

ta có:4^10=(2^2)^10=2^20

        8^15=(2^3)^15=2^45

2^20*2^45=2^65

Vậy 4^10*8^15=2^65

nhé!

\(4^{10}\times8^{15}\)

\(=\left(2^2\right)^{10}\times\left(2^3\right)^{15}\)

\(=2^{20}\times2^{45}\)

\(=2^{65}\)

\(4^{15}\times5^{30}\)

\(=\left(2^2\right)^{15}\times5^{30}\)

\(=2^{30}\times5^{30}\)

\(=\left(2\times5\right)^{30}\)

\(=10^{30}\)

\(27^{16}\div9^{10}\)

\(=\left(3^3\right)^{16}\div\left(3^2\right)^{10}\)

\(=3^{48}\div3^{20}\)

\(=3^{28}\)

4^10 . 8^15

= (2^2)^10 . (2^3)^15

= 2^20 . 2^45

= 2^20 + 45

= 2^65

4^15 . 5^30

= (2^2)^15 . 5^30

= 2^30 . 5^30

= 10^30

27^16 : 9^10

= (3^3)^16 : (3^2)^10

= 3^48 : 3^20

= 3^48 - 20

= 3^28

mình cũng hỏi về cái này gấp nha ai biết trả lời câu nào thì trả

\(a,4^{15}\cdot5^{30}\\ =4^{15}\cdot25^{15}\\ =\left(4\cdot25\right)^{15}\\ =100^{15}\\ b,27^{16}:9^{10}\\ =3^{48}:3^{20}\\ =3^{48-20}\\ =3^{28}\)

a) \(=2^{2^{15}}\cdot5^{30}\)

\(=2^{30}\cdot5^{30}\)

\(=10^{30}\)

b) \(=3^{3^{16}}:3^{2^{10}}\)

\(=3^{48}:3^{20}\)

\(=3^{28}\)

a. \(4^{10}.8^{15}=\left(2^2\right)^{10}.\left(2^3\right)^{15}=\)\(2^{20}.2^{45}=2^{20+45}=2^{65}\)

b.\(4^{15}.5^{30}=4^{15}.\left(5^2\right)^{15}=4^{15}.\)\(25^{15}=\left(4.25\right)^{15}=100^{15}\)

c.\(27^{15}:9^{10}=\left(3^3\right)^{15}:\left(3^2\right)^{10}=3^{45}:3^{20}\)\(=3^{45-20}=3^{25}\)

Tính :

a) 4¹⁰ . 8¹⁵ = ( 2² )¹⁰ . ( 2³ )¹⁵ = 2²⁰ . 2⁴⁵ = 2^{20 + 45} = 2⁶⁵

b) 4¹⁵ . 5³⁰ = ( 2² )¹⁵ . 5³⁰ = 2³⁰ . 5³⁰ = ( 2.5 )³⁰ = 10³⁰

c) 27¹⁶ : 9¹⁰ = ( 3³ )¹⁶ : ( 3² )¹⁰ = 3⁴⁸ : 3²⁰ = 3^{48 - 20} = 3²⁸

\(4^{10}.8^{13}=2^{20}.2^{39}=2^{59}\)

\(27^{16}:9^{10}=3^{48}:3^{20}=3^{28}\)

\(\left(2^2\right)^{10}.\left(2^3\right)^{13}=2^{20}.2^{39}=2^{20+39}=2^{59}\)

\(\left(3^3\right)^{16}.\left(3^2\right)^{10}=3^{48}.3^{20}=3^{48+20}=3^{68}\)
