若m为正整数,3^2m*4^2m*36^m/72^2m等于若m为正整数,3^2m*4^2m*36^m/72^2m等于若m为正整数,3^2m*4^2m*36^m/72^2m等于3^2m*4^2m*36^

若m为正整数,3^2m*4^2m*36^m/72^2m等于
若m为正整数,3^2m*4^2m*36^m/72^2m等于

若m为正整数,3^2m*4^2m*36^m/72^2m等于
3^2m*4^2m*36^m/72^2m
=9^m*16^m*36^m / 72^m*72^m
=154^m*36^m / 72^m*36^m*2^m
=1^m
=1
楼上错了,知道吗?

3^2m*4^2m*36^m/72^2m
=9^m*8^m*36^m / 72^m*72^m
=72^m*36^m / 72^m*36^m*2^m
=1/2^m

=1
