Solve the following exercise:
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Convert the expression:
This results in a single square root.
Step 2: Simplify inside the square root:
Step 3: Calculate the square root:
Thus, combining all parts logically, we resolve the expression:
Therefore, the solution to the problem is .
Choose the largest value
Yes! The key rule is . You combine all the expressions under one square root, then simplify what's inside.
Multiply fractions normally: . Remember to multiply numerators together and denominators together.
When , we get an improper fraction. Converting gives us because 9 ÷ 2 = 4 remainder 1.
Use the rule . So .
In this problem, both 81 and 4 are perfect squares (9² and 2²), so we get exact answers. If they weren't perfect squares, you'd leave the answer in radical form.
