Logarithmic Function Definition In mathematics, the logarithmic function is an inverse function to exponentiation. The logarithmic function is defined as. For x > 0 , a > 0, and a ?1, y= loga x if and only if x = ay.

Step 1: Use the properties of the logarithm to isolate the log on one side. Step 2: Apply the definition of the logarithm and rewrite it as an exponential equation. Step 3: Solve the resulting equation. Step 4: Check your answers.

The "basic" logarithmic function is the function, y=logbx, where x, b>0 and b?1.

Logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.

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.

The laws apply to logarithms of any base but the same base must be used throughout a calculation. This law tells us how to add two logarithms together. Adding log A and log B results in the logarithm of the product of A and B, that is log AB. The same base, in this case 10, is used throughout the calculation.

Correct answer: In order to eliminate the log based ten, we will need to raise both sides as the exponents using the base of ten. The ten and log based ten will cancel, leaving just the power on the left side. Change the negative exponent into a fraction on the right side.

To solve this type of problem:Step 1: Change the Base to 10. Using the change of base formula, you have.Step 2: Solve for the Numerator and Denominator. Since your calculator is equipped to solve base-10 logarithms explicitly, you can quickly find that log 50 = 1.699 and log 2 = 0.3010.Step 3: Divide to Get the Solution.Dec 14, 2020

Laws of logarithms These laws can be applied on any base, but during a calculation, the same base is used. Example: log 2 5 + log 2 4 = log 2 (5 × 4) = log 2 20. log 10 6 + log 10 3 = log 10 (6 x 3) = log 10 18.
