Question

What is the value of the expression 1/2 • 2^3 + 7?

Answer 1

The value of the expression 1/2 • 2^3 + 7 can be found by following the order of operations, also known as PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

In this expression, there are no parentheses or exponents, so we move on to multiplication and division.

First, we calculate 1/2, which is equal to 0.5.

Next, we calculate 2^3, which means multiplying 2 by itself three times: 2 • 2 • 2. This equals 8.

Now we have 0.5 • 8 + 7.

Multiplying 0.5 by 8 gives us 4.

Finally, we add 4 and 7 to get the final answer: 11.

So, the value of the expression 1/2 • 2^3 + 7 is 11.

Answer 2

1/2 and one 2 can be multiplied to 1 so the equation turns to:

2^2+7=4+7=11
