Answer :
Logx(81)=4
x^4=81 (The result of a log expression becomes the exponent. So 4, becomes the exponent of the log's base and we end up having x^4. )
x=3 (because 3^4=81)
x^4=81 (The result of a log expression becomes the exponent. So 4, becomes the exponent of the log's base and we end up having x^4. )
x=3 (because 3^4=81)
The answer to logx (81)= 4 is 3.
What is Logarithm?
This refers to the quantity that a power that has a fixed base must be raised to a certain power.
Hence, given that
Logx(81)=4
We recall that one of the laws of the logarithm is the exponential law.
Therefore, 4 becomes the exponent which would be x^4 and this can be expressed as:
3^4 = 81
In conclusion, the answer to x is 3
