Question

\(\frac{11.3^{22}.3^7-9^{15}}{\left(3^{14}\right)^2}\)

bài toán là thực hiện phép tính giúp mk nha 

Answer 1

\(\frac{11.3^{22}.3^7-9^{15}}{\left(3^{14}\right)^2}\)

\(=\frac{11.3^{29}-3^{30}}{3^{28}}\)

\(=\frac{3^{29}.\left(11-3\right)}{3^{28}}\)

\(=3.8=24\)

Answer 2

\(\frac{11.3^{22}.3^7-9^{15}}{ \left(3^{14}\right)^2}\)

= \(\frac{11.3.3^{21}.3^7-\left(3^2\right)^{15}}{\left(3^{14}\right)^2}\)

= \(\frac{33.3^{28}-3^{30}}{3^{28}}\)

= \(\frac{33.3^{28}-3^{28}.9}{3^{28}}\)

= \(\frac{3^{28}.\left(33-9\right)}{3^{28}}\)

= \(\frac{24}{1}=24\)

Answer 3

\(\frac{11.3^{22}.3^7-9^{15}}{\left(3^{14}\right)^2}\)

\(=\frac{11.3^{29}-3^{30}}{3^{28}}\)

\(=\frac{3^{29}.\left(11-3\right)}{3^{28}}\)

\(=3.8\)

\(=24\)
