**KEY POINTS**

A square root of a number must be squared (multiplyed by itself or raised to the power of 2) to give the number_ ANY positive number has 2 square roots- 1 positive, 1 negative

The cube root of a number has to be cubed (raised to the power of 3) to give the number.

**STANDERED INDEX FORM**

Index Notation useful for showing very large and very small numbers

14 000 000= 1.4 (number between 1 and 10)*10*10*10*10*10*10= 1.4*10_6

(Underscore on previous line means 10 to the power of 6)
