The inverse relation is the logarithm in base z. Ie., if y = zx, then x = logz y, read as "the log in base z of y". It may be helpful to look at the properties of logarithms (really just the ordinary properties of exponents), in particular the change of base formula.Werg22 said:in an equation such as:
y=z^x
How to find out the value of x in function of y and z? I'm sure there is a mathematical relaionship... thank you in advance.
That is because Log() on Google refers to Log10. In order to get 4, just use Log99, or if Google doesn't allow change of base, change the base yourself by dividing your base ten logarithm by Log10(99).eNathan said:But if I have 96059601 = 99^4 then Log(96059601) = 7.98254078 which does not result in the original '4', probally because the 99 is not taken into account I am not sure.
PS.Google is the best calculator ever
A power is a mathematical operation that involves raising a number to a certain exponent.
The value of a power can be determined by multiplying the base number by itself the number of times indicated by the exponent. For example, 23 would be calculated as 2 x 2 x 2, resulting in a value of 8.
The base number is the number that is being raised to a certain power. It is the number that is multiplied by itself the number of times indicated by the exponent.
An exponent is a number that indicates how many times the base number should be multiplied by itself in a power operation. It is represented by a superscript number above the base number.
Yes, a power can have a negative exponent. This indicates that the base number should be divided by itself the number of times indicated by the exponent. For example, 2-3 would be calculated as 1 / (2 x 2 x 2), resulting in a value of 1/8 or 0.125.
