True.

2 is the base and 3 is the exponent part

Answer 2

a) 4 superscript 2 and 4 squared

b) True

Explanation:

The expression, 4^2, can be read using the phrases

4 superscript 2 and 4 squared.

In indices, any value that is on top of the base number is known as the power of such number or its superscript. It means that the base number will be multiplied by itself the number of times the value of the power. For example for 4², the base number 4 will be multiplied by itself twice.

b) In the expression 2³, the 2 is called the base. This statement is true because the value above which a superscript is raised is called its base number. For example in the equation a^b, a will serve as the base number.
