By defining how exponents work, we conclude that 4^3 = 64, so the correct option is A.
<h3>
How to find the cube of 4?</h3>
Let's remember how exponents work.
If we have a number a to the exponent n:
a^n
It means that we need to multiply the number a by itself n times.
Then, in this case:
4^3
Can be rewritten to.
4*4*4
Now we can solve that product:
4*4*4 = (4*4)*4 = 16*4 = 64
Then we conclude that the correct option is A
4^3 = 64

Step-by-step explanation:
It says area= 80.5. Try it and I promise you all it will be right.
 
        
             
        
        
        
The length/width ratio is 3/1
.
<em>l</em> = 6.6 × 10⁻⁶ m; <em>w</em> = 2.2 × 10⁻⁶ m
<em>l</em>/<em>w</em> = 6.6 × 10⁻⁶ m/2.2 × 10⁻⁶ m = 3/1
