Properties Of Indices And Logarithms
Gbogbo ọrọ náà
Indices and logarithms are two sides of the same coin. One tells you the result of repeated multiplication; the other asks which power produced a given result. Together they unlock a toolkit for simplifying expressions, solving exponential equations and converting between bases that appears throughout the Further Pure Mathematics course.
In this topic you will master the seven index laws, the four core logarithm laws, the change of base formula, and the technique for solving equations where the unknown sits in the exponent. Every rule is derived from the same principle, so once you see the pattern the whole system clicks into place.
Ebumnobi
- Use and apply properties of indices and logarithms, including change of base
- Know that log_a(xy) = log_a(x) + log_a(y)
- Know that log_a(x/y) = log_a(x) - log_a(y)
- Know that log_a(x^k) = k log_a(x)
- Know that log_a(a) = 1 and log_a(1) = 0
- Solve equations of the form a^x = b
- Use the change of base formulae
