Question

Tính : 3^7.2^8 / 6^7

Answer 1

\(\dfrac{3^7.2^8}{6^7}\)

=\(\dfrac{\left(3.2\right)^{7+8}}{6^7}\)

=\(\dfrac{6^{15}}{6^7}\)

\(6^{15}:6^7=6^{15-7}\)

=\(6^8\)

Answer 2

\(\dfrac{3^7.2^8}{6^7}\) = \(\dfrac{3^7.2^8}{\left(3.2\right)^7}\) = \(\dfrac{3^7.2^8}{3^7.2^7}\) = \(\dfrac{1.2}{1.1}=2\)

Answer 3

3^7.2^8/6^7

=3^7.2^8/6^7

=3^7.2^8

=6^7=3^7.2^7

=3^7.2^8=559872

=3^7.2^7=279936

559872/279936=559872:279936

=2
