jarptica [38.1K]

E $\alpha fg$
e=mfg
Where m is a constant of proportionality;
e=4, f=2 and g=8
Then;
4=m*2*8

The method is known as SQ3R. The SQ3R method is a reading comprehension strategy that teaches pupils how to recognize essential facts and keep material from their textbooks in their memories.

Recalling information on purpose compels us to "take out" our prior knowledge and investigate the basis of our current understanding.
