Q
Q: If a = 1 and b = 2, what is the value of a³ + b³?
Solution:
a³ + b³ = 1³ + 2³ = 1 + 8 = 9.
Steps: 4
Show Steps
Step 1: Identify the values of a and b. Here, a = 1 and b = 2.
Step 2: Calculate a³ (a cubed). This means multiplying a by itself three times: 1 * 1 * 1 = 1.
Step 3: Calculate b³ (b cubed). This means multiplying b by itself three times: 2 * 2 * 2 = 8.
Step 4: Add the results from Step 2 and Step 3 together: 1 + 8 = 9.
