Problem 10 - College Algebra

Question

Evaluate each expression or indicate that the root is not a real number. $$\sqrt{144}+\sqrt{25}$$

Step-by-Step Solution

Answer

The solution to the problem is 17

Step 1: Find the Square Root of the First Number

The square root of 144 is the number that when multiplied by itself gives 144. That number is 12 because \(12 \times 12 = 144\).

Step 2: Find the Square Root of the Second Number

The square root of 25 is the number that when multiplied by itself gives 25. That number is 5 because \(5 \times 5 = 25\).

Step 3: Add the Two Numbers Together

Now add these two numbers together: \(12+5 = 17\).
