Week Four - Turei 11th Mei

Today we extended our power rules from Monday, to allow for terms which have coefficients (numbers out the front).

• When we multiply we add powers, and we multiply the numbers out the front.

e.g 4a^2 x 3a^5 = 12a^7

• When we divide we subtract powers, and we simplify the numbers like a fraction on a calculator
  

e.g. 12a^7/4a^4 = 3a^3

• When there are brackets we multiply each power with the one outside, and we calculate the number to the power of the outside power.

e.g. (3a^3 b)^2 = 9a^6 b^2
