E1) I have a three-year-old friend. He has a lot of toy cars to play with. Playing with him once, I divided the cars into two sets. One set was more spread out and had 14 cars in it. The other set had 15 cars, but they were placed more closely. He had the choice of taking the set with more cars. He made the correct choice. From this, which of the following statements would you deduce? What are the reasons for your choice?
a) He can count upto 20.
b) He can perceptually distinguish between large sets.
c) He just made the choice by chance, and may not be able to repeat it.
d) He may be able to do a lot of things with cars, but not with other objects.

We know that 2 4 = 16 and also that 2 is referred to as the base, 4 as the index or power or the exponent. The same if expressed in terms of logarithms would be log 2
