Bea: W^2=20
What is w?
W
2 = 20
you need to get rid of the 'square'
What is the opposite of 'square'
Think about this
4
2 = 16
What do you have to do to 16 to get back to 4? (NOTE: It is
not divide)
or
7
2= 49
What do you have to do to 49 to get back to 7? (The same thing as before)
or
another way of looking at it.
What is sqrt( 8
2)
Anyway if you can work out what I am talking about, that is what you have to do to both sides.
