YEAR 10 · EXPONENTIAL RELATIONSHIPS

Topic review.

Check the key ideas, then put them together independently.

QUICK RECAP

Connect the ideas

Choose an index law from the operation; do not apply product laws to sums.

Fractional powers connect with roots. Keep even-root domains and log inputs valid.

Simplify surds exactly and rationalise using equivalent fractions.

Exponential change multiplies by a fixed factor over equal input intervals.

Logarithms invert powers; logarithmic scale differences describe ratios.

Use graphs, tables and context to choose and check a model; round at the end.
