帮助计算几个对数问题

解决方法:2。计算:(1)log(3)2/log(27)64 = log(3)2/log(3)4。

=log(4)2

=1/2.

(2)2^[4+log(2)3=2^[log(2)16+log(2)3]

=2^log(2)48

=48.

25^[1/2log(5)27+2log(5)2]=5^[log(5)27+4log(5)2]

=5^[log(5)27+log(5)16]

=5^log(5)432

=432.

(3)0.064^( - 1/3) - ( - 7/8)^0+[( - 2)^3]^( - 1/3)+0.01^1/2

=1/0.4 - 1+( - 2)^( - 1)+0.1

=2.5 - 1 - 0.5+0.1

=1.1.
