An Exponent Question
Which mental path do you think is easiest for beginning students? (Analytical, numerical, graphical, algebraic?) Would you give a different hint to beginning students than to advanced students?
Will the average of \( 2^{48} \) & \( 2^{50}\) be less than, greater than, or equal to \( 2^{49} \)?
Can you find the actual average? (without a calculator!)
#mathchat #SATPrep
Will the average of 2^48 & 2^50 be <,>, or = 2^49?
Hint: Think graphically!
Now show the actual avg is 1.25×2^49.
