Chapter 1: Q 137. (page 39)

In the following exercises, evaluate the following expressions.
$a^{2} + b^{2} when a = 3, b = 8$

Short Answer

Expert verified

The required value is 73.

Step by step solution

Step 1. Given information.

The given expression is:

$a^{2} + b^{2}$

We have to evaluate the given expression for $a = 3 and b = 8$ .

To evaluate an expression means to find the value of the expression when the variable is replaced by a given number.

Step 2. Replace a with 3 and b with 8 in the given expression.

$a^{2} + b^{2} = 3^{2} + 8^{2}$

Follow the order of operations,

$= 3 \cdot 3 + 8 \cdot 8 = 9 + 64 = 73$

The value of $a^{2} + b^{2} when a = 3, b = 8$ is 73.
