2^x=64
2^x=2*2*2*2*2*2
2^x=2^6
x=6
2^x=2*2*2*2*2*2
2^x=2^6
x=6

2^x=64
64=8*8=(2^3)*(2^3)=2^(3+3)=2^6
so :x=6

2^x = 64
Since 2^6 = 64
So x = 6
Since 2^6 = 64
So x = 6

m1:(form 4)
2^x=64
x log 2 = log 64(both sides take log)
x=(log 64)÷(log 2)
x=6
m2:(form3)
2^x =64
2^x =2^6(compare with the power of 2 sides)
x=6
2^x=64
x log 2 = log 64(both sides take log)
x=(log 64)÷(log 2)
x=6
m2:(form3)
2^x =64
2^x =2^6(compare with the power of 2 sides)
x=6

2^x = 64
2^x = 2^6
By comparing the indices of both sides, we can find that
x = 6#
p.s. 係列式...唔係列識...
