Question: 1 / 400

What is the value of the expression 2² + 3×5?

To find the value of the expression $ 2^2 + 3 \times 5 $, start by performing the operations according to the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

First, calculate $ 2^2 $, which is the exponentiation part of the expression.

2^2 = 4

Next, move on to the multiplication part of the expression, which is $ 3 \times 5 $.

3 \times 5 = 15

Now, combine the results from both operations. You will add the result of $ 2^2 $ to that of $ 3 \times 5 $:

4 + 15 = 19

Thus, the final value of the expression $ 2^2 + 3 \times 5 $ is 19.

This confirms that 19 is indeed the correct answer as it directly results from accurately applying the order of operations to evaluate the expression.
