Question

What is the value of the expression 3+2x (with an exponent of 3 on top of x) when x = 2?
A. 67
B. 19
C. 10651
D. 75

Answer 1

Answer:

A. 67

Step-by-step explanation:

3+2(2)^3

The first thing you would do is distribute the 2 and you would get

3+(4)^3

The next thing you would do is the exponent

3+(4*4*4) = 3+64

Then you would just add 3

64+3= 67

So the answer is A. 67.
