Logarithmic
Storyboard Text
- Good morning class today we will learn how to evaluate and solve logarithmic functions with unknown variables.
- Logarithms and exponents are two topics in mathematics that are closely related. Therefore it is useful we take a brief review of exponents.
- Rewrite exponential function 72 = 49 to its equivalent logarithmic function.
- Rewrite exponential function 72 = 49 to its equivalent logarithmic function.
- An exponent is a form of writing the repeated multiplication of a number by itself. An exponential function is of the form f (x) = b y, where b > 0 < x and b ≠ 1. The quantity x is the number, b is the base, and y is the exponent or power.
- Rewrite exponential function 72 = 49 to its equivalent logarithmic function.SolutionGiven 7^2 = 64Here, the base = 7, exponent = 2 and the argument = 49. Therefore, 7^2 = 64 in logarithmic function is;⟹ log 7 49 = 2
- Now lets try solving, Here's an example.
- Now, would anyone like to answer this next problem?
- Write the logarithmic equivalent of 53= 125.
- That is how you solve logarithmic function.
- ME ME ME!
- Write the logarithmic equivalent of 53= 125.
- ME, I want to answer!
