Question

Rút gọn phép tính 2³ * 3⁵ ab³ * ( 2 * 3² a³ b² )

Answer 1

\(2^3\cdot3^5ab^3\cdot\left(2\cdot3^2a^3b^2\right)\)

\(=8\cdot243\cdot ab^3\cdot2\cdot9\cdot a^3b^2\)

\(=1944\cdot18\cdot\left(a\cdot a^3\right)\cdot\left(b^3\cdot b^2\right)\)

\(=34992a^4b^5\)

Answer 2

2³.3⁵ab³.(2.3²a³b²)

= (2³.2).(3⁵.3²).(a.a³).(b³.b²)

= 2⁴.3⁷a⁴b⁵

= 34992a⁴b⁵
