3^2 nhân 1/243 nhân 81^2 nhân 1/3^2 mọi người giúp e giải với ạ

 

 

Answer 1

Nông Hà Thanh

\(3^2.\frac{1}{243}.81^2.\frac{1}{3^2}\)

\(=\frac{3^2}{3^5}.\frac{81^2}{3^2}\)

\(=\frac{1}{3^3}.27^2\)

\(=\frac{27^2}{3^3}\)

\(=\frac{3^6}{3^3}\)

\(=3^2\)

\(=9\)

Answer 2

=3^2*1/3^5*3^4/2*1/3^2

=1/6

Answer 3

Em cảm ơn

Answer 4

=(3^2*3^8)*(1/3^5*1/3^2)

=3^10*1/3^7

=3^3

=27

Answer 5

\(3^2.\frac{1}{243}.81^2.\frac{1}{3^2}\)

\(=\frac{3^2}{3^5}.3^8.\frac{1}{3^2}\)

\(=\frac{1}{3^3}.3^6\)

\(=\frac{3^6}{3^3}\)

\(=3^3=27\)

Answer 6

3^2.1/243.81^2.1/3^2

=3^2.1/3^5.81^2.1/3^2

=(3^2.81^2).(1/3^5.1/3^2)

=243^2.1/3^7

=243^2.1/243^2=1
