Question

5²⁰ : ( 5¹⁵ . 6 + 5¹⁵ . 19)

giải nhanh hộ mình nhé

cảm ơn nhiều

Answer 1

5²⁰ : ( 5¹⁵ . 6 + 5¹⁵ . 19)

=5^20: [5^15(6+19)]

=5^20:5^15.5^2

=5^3

Answer 2

\(5^{20}\div\left(5^{15}.6+5^{15}.19\right)\)

\(=\)\(5^{20}\div\left[5^{15}.\left(6+19\right)\right]\)

\(=\)\(5^{20}\div\left[5^{15}.25\right]\)

\(=\)\(5^{20}\div\left[5^{15}.5^2\right]\)

\(=\)\(5^{20}\div5^{17}\)

\(=\)\(5^3\)

\(=\)\(125\)

Answer 3

5²⁰ :(5¹⁵.6+5¹⁵.19)

=5²⁰:(5¹⁵.(6+19) )   

=5²⁰:(5¹⁵.25)

=5²⁰:(5¹⁵.5²)=5²⁰:5¹⁷=5³
