The (32/4)^x is equal to the 8^x.
We have given that,
A. (32/4)^x
B. 32^x/4
C. 8*8^x+1
D. x^4
E. 32^x/4^x
F. 8*8^x-1
We have to determine the expression equivalent to the 8^x.
<h3>What is the expression?</h3>
An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Therefore the expression equivalent to the 8^x is A.
That is,
Therefore the (32/4)^x is equal to the 8^x.

Answer:
E(X) = 17.4
Step-by-step explanation:
We can calculate the expected value of a random X variable that is discrete (X takes specific values ) as:
E(X) = ∑xp(x) where x are the specific values of x and p(x) the probability associated with this x value.
In this way the expexted value is
E(X) = ∑xp(x) =(16*0.6)+(18*0.3)+(20*0.2) = 8+5.4+4 = 17.4
What do you mean by that?
I think there are two solutions, 63 or 147:
63 = 3² x 7, factors 1 | 3 | 7 | 9 | 21 | 63<span>
147 = 3 x 7</span>², factors 1 | 3 | 7 | 21 | 49 | 147
