Chapter 1, Problem 11CST

To determine

To Evaluate: An expression involving two numbers containing addition and square operations.

Answer to Problem 11CST

The value of the expression is $28$ .

Explanation of Solution

Given Information: The expression to be evaluated is $x+y^2$ .

Also, $x=3$ and $y=5$ .

Concept Used:

• The expression is to be evaluated according to the Order of Operations.
• The product of two numbers with the same sign is positive.

Put the values of $x$ and $y$ in the expression $x+y^2$ to get $3+5^2$ .

In the Order of Operations, products are to be evaluated before additions.

Also, $5\times 5$ is positive as both the numbers involved in the product have the same sign.

So, $3+5^2=3+5\times 5=3+25=28$
