8²x5²

giải giúp mk với

Answer 1

2⁶ x 5⁶ = ( 2 x 5 )⁶ = 10⁶ = 1 000 000 

4³ x 5³ = ( 4 x 5 )³ = 20³ = 8 000

6³ x 5³ = ( 6 x 5 )³ = 30³ = 27 000

8² x 5² = ( 8 x 5 ) ² = 40² = 160 

Answer 2

\(2^6.5^6=10^6=100000\)

\(4^3.5^3=20^3=8000\)

\(6^3.5^3=30^3=27000\)

\(8^2.5^2=40^2=1600\)

Answer 3

\(2^6\cdot5^6=\left(2\cdot5\right)^6=10^6=1000000\)

\(4^3\cdot5^3=\left(4\cdot5\right)^3=20^3=8000\)

\(6^3\cdot5^3=\left(6\cdot5\right)^3=30^3=27000\)

\(8^2\cdot5^2=\left(8\cdot5\right)^2=40^2=1600\)
