Q
Q: If a = 4 and b = 5, what is the value of a² + b²?
Solution:
a² + b² = 4² + 5² = 16 + 25 = 41.
Steps: 4
Show Steps
Step 1: Identify the values of a and b. Here, a = 4 and b = 5.
Step 2: Calculate a squared (a²). This means multiplying a by itself: 4 * 4 = 16.
Step 3: Calculate b squared (b²). This means multiplying b by itself: 5 * 5 = 25.
Step 4: Add the results from Step 2 and Step 3 together: 16 + 25 = 41.
