Fractional Indices and Introduction to Logarithms

What is the square root of 64? What about the cube root of 27? These involve fractional indices. This chapter introduces fractional indices, which represent roots, and then transitions to logarithms, the inverse of indices, which help solve complex equations.

• Understand and apply fractional indices.
• Define and convert between exponential and logarithmic forms.
• Evaluate simple logarithms.
• Understand the relationship between indices and logarithms.
