Question

\(\dfrac{6^5.\left(-12\right)^6}{\left(-4\right)^9\left(-3^{ }\right)^{10}}\) Giup gap a

Answer 1

\(\dfrac{6^5.\left(-12\right)^6}{\left(-4\right)^9\left(-3\right)^{10}}\)

\(=\dfrac{6^5.12^6}{\left(-4\right)^9.3^{10}}\)

\(=\dfrac{2^5.3^5.2^{12}.3^6}{\left(-1\right).2^{18}.3^{10}}\)

\(=\dfrac{2^{17}.3^{11}}{\left(-1\right).2^{18}.3^{10}}\)

\(=\dfrac{3}{\left(-1\right).2}\)

\(=\dfrac{-3}{2}\)
