Question

若2的M次方等于3，4的N次方等于8，则2的3M+2N-1等于多少

Answer 1

由题意可知：
2的3M次方 = 3X3X3=27
2的2N次方 = 4的N次方 = 8
所以：2的3M+2N-1次方 = 27X8/2=108

Answer 2

2的3M次方等于27
4的N次方等于8等于2的2N次方等于8
所以结果为27*8/2=108

Answer 3

2的3M+2N-1次方等于
2的3M次方×2的2N次方÷2的1次方
=2的M次方的3次方×4的N次方÷2
=3的3次方×8÷2
=27*4
=108

Answer 4

2的（3M+2N-1）次方
=2^3m*2^2n/2
=27*8/2
=108

Answer 5

2^m=3,
4^n=8
2^(3m+2n-1)
=(2^m)�0�6(2^n)�0�5/2
=27*64/2
=864
