Question

rút gọn pso

\(\frac{3^{10}.\left(-5\right)^{21}}{\left(-5\right)^{21}.3^{12}}\)

nhanh nha

Answer 1

\(=\frac{1}{3^2}=\frac{1}{9}\)

Answer 2

\(\frac{3^{10}.\left(-5\right)^{21}}{\left(-5\right)^{21}.3^{12}}\)\(=\)\(\frac{1}{3^2}\)\(=\frac{1}{9}\)

Answer 3

\(\frac{3^{10}.\left(-5\right)^{21}}{\left(-5\right)^{21}.3^{12}}\)

\(=\frac{3^{10}.\left(-5\right)^{21}}{\left(-5\right)^{21}.3^{10}.3^2}\)

\(=\frac{1}{3^2}=\frac{1}{9}\)

Study well ! >_<

Answer 4

\(\frac{3^{10}.\left(-5\right)^{21}}{\left(-5\right)^{21}.3^{12}}\)

\(=\frac{3^{10}}{3^{12}}\)

\(=\frac{1}{3^2}\)

\(=\frac{1}{9}\)
