Writing One Number As A Power Of Another | Year 1 Pure | A Level Maths

Writing one number as a power of another is a key algebraic skill that supports later work on logarithms and exponential equations. In this lesson you will use the laws of indices to rewrite numbers in a chosen base, manipulate expressions involving powers of the same base, and recognise common bases such as 2, 3, 5 and 10. This technique is invaluable when solving equations of the form a^x = b and when simplifying complex algebraic expressions.
