How do you convert an exponential equation to logarithmic form?
Right remember that was the inverse form and then so we said okay well that then goes to y equals log base a of x. So that’s how we converted we said from here we went to there.

What is the logarithmic form of the exponential equation?
Logarithmic functions are the inverses of exponential functions. The inverse of the exponential function y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay.
How do you convert an exponential equation?
And for number or letter c i have logarithm of x base 3 equal to 2 in my head i know i can convert it into exponential by looking at the base 3 raised to 2 is equal to x. 3 raised to 2 is equal to x.
How do you calculate logarithmic form?
The equation x = 2y is often written as a logarithmic function (called log function for short). The logarithmic function for x = 2y is written as y = log2 x or f(x) = log2 x. The number 2 is still called the base.

Is exponential the same as logarithmic?
An exponential function has the form ax, where a is a constant; examples are 2x, 10x, ex. The logarithmic functions are the inverses of the exponential functions, that is, functions that “undo” the exponential functions, just as, for example, the cube root function “undoes” the cube function: 3√23=2.

Exponential Function Formula
An exponential function is defined by the formula f(x) = ax, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x. The exponential function is an important mathematical function which is of the form.

What is EXP on a calculator?
(‘Exp’ stands for ‘exponent’.) This tells the calculator that the next number you enter will be a power of 10 and that you are working in scientific notation. The ‘e’ now showing on the display indicates that the number you have entered is displayed in scientific notation. 3.e + 0.
