In math, that may either refer to changing the base of the number system (for example, change from decimal (base 10) to binary (base 2)); or it may refer to changing logarithms, from one base to another - for example, common (base-10) logarithms to natural (base-e) logarithms.

The answer depends on the context. The formula for changing the base between decimal, binary, octal and so on is different to that for logarithms.
The answer depend on the context: base as in binary, octal, decimal, hexadecimal or base as in exponential notation / logarithms.
Use the change of base formula. The change of base formula goes like this: logbx = (logx)/(logb) the logs on the right side can be any base, though you should probably use log10 because that's what your calculator will use.
The area of a triangle can be calculated using the formula: Area = 0.5 x base x height. Given the base is 12cm and the height is unknown, the area cannot be determined without the height measurement. To find the area, you would need to know the specific value of the height in order to plug it into the formula and calculate the area of the triangle accurately.
There is no such formula
slope is rise over run. so the change in slope can be determined by the change in Y over the change in X. once you get the slope of the line you can plug a point into the point slope formula (Y-Y1)=m(X-X1). solve for Y to put it into Y=mx+b form.
It says so in the formula
