Answer :

To determine the value of the exponential expression [tex]\( 4^3 \)[/tex], let's break down the steps involved in calculating it:

1. Understand the problem:
- The term 'exponential expression' [tex]\( 4^3 \)[/tex] represents '4 raised to the power of 3'.

2. Decompose the expression:
- [tex]\( 4^3 \)[/tex] means multiplying the number 4 by itself three times.

3. Perform the multiplication:
- First, calculate [tex]\( 4 \times 4 \)[/tex] which equals 16.
- Next, multiply the result by 4 again.

[tex]\[ 4 \times 4 = 16 \][/tex]

[tex]\[ 16 \times 4 = 64 \][/tex]

So, the value of the exponential expression [tex]\( 4^3 \)[/tex] is [tex]\( 64 \)[/tex].

4. Identify the correct answer:
- From the given options, the correct value is:

[tex]\[ \text{A. 64} \][/tex]
