Q
Q: If a = 3 and b = 4, what is the value of a^2 + b^2? (2019)
Solution:
a^2 = 9 and b^2 = 16, so 9 + 16 = 25.
Steps: 4
Show Steps
Step 1: Identify the values of a and b. Here, a = 3 and b = 4.
Step 2: Calculate a squared (a^2). This means multiplying a by itself: 3 * 3 = 9.
Step 3: Calculate b squared (b^2). This means multiplying b by itself: 4 * 4 = 16.
Step 4: Add the results from Step 2 and Step 3 together: 9 + 16 = 25.
