You learn how to work with indices and logarithms by using the rules that link powers, roots, and repeated multiplication. This matters because it helps you simplify expressions quickly and solve number problems that often appear in Senior High School maths.
You should already be comfortable with multiplication, division, powers, and simple fractions. It also helps if you can read and write numbers in index form.

One question from this skill's own question bank, shown with its full working.
