fractional coefficients
What fractional coefficients means in Mathematics A-Level, as defined for WJEC.
Definition of fractional coefficients
Check what you remember
Read the wording for your board, then hide it and explain fractional coefficients in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
Coefficients such as k = 1/2 give (1/2) logₐ x = logₐ (x^(1/2)) = logₐ (√x), and k = −1/2 gives (−1/2) logₐ x = logₐ (1/√x).
