Understanding Logarithmic Scales

The video tutorial explains how to determine the value of points on a logarithmic scale, focusing on a common log scale where each tick mark represents a power of 10. It covers the calculation of values for points A, B, C, and D on the scale, converting exponential equations to logarithmic form, and understanding the relationship between the exponent and the common log of X.

What does each tick mark represent on a logarithmic scale?

• A power of 10

• A power of 20

• A power of 2

• A power of 5
