✔ 最佳答案
兩個方法(1)
2^x=64
2^x=2^6
x=6
------------
(2)
2^x=64
xlog2=log64(未知呢個你學左未)
x=6

方法1
2^x = 64
ln (2^x) = ln 64
x ln 2 = ln 64
x = ln 64 / ln 2
方法2
2^x = 64
2^x = 2^6
x = 6
2^x = 64
ln (2^x) = ln 64
x ln 2 = ln 64
x = ln 64 / ln 2
方法2
2^x = 64
2^x = 2^6
x = 6

2^x=64
lg 2^x=lg2^8
xlog2=8log2
x=8
lg 2^x=lg2^8
xlog2=8log2
x=8

use log^^
2007-01-05 1:53 am
2^x = 2*2*2*2*2*2
x=6
x=6
