LESSON 3.1
APPLY
If y = 4, then what would be the outcome of y2?
LESSON 3.1
APPLY
If y = 4, then what would be the outcome of y2?
If y = 4 then y2 is equal to 42
therefore 42 or 4 x 4 is equal to 16
LESSON 3.1
ANALYZE Write a statement of how these errors were made
42 = 8 The base and power were multiplied together
42 = 6 The base and power were added together
Then write the correct answer for 42 42 = 16
