Week 2 in Math 10

The thing that I leran in this week is ‘how to convert to entire radicals’ , an entire radical of index 3 may be expressed as a mixed radical when the highest perfect cube has been factored out of the entire radical.A mixed radical of index 3 may be expressed as an entire radical by converting the number outside the radical symbol into a radical and then multiplying it by the radicand.

(Pic: I drew it by myself)

Entire to mixed

e.g. \sqrt[3]{54}=\sqrt[3]{2 \cdot 3\cdot 3\cdot3}=3\sqrt[3]{2}

#3 tell us how many in a group

 

This also works for other roots (4th,5th,6th,7th…)
