Answer:
The correct answer is 64 times Geri’s original answer
Step-by-step explanation:
Given
Gari's Answer: 2³
Correct Answer: 2⁹
Required:
Relationship between both answers
Let Gari's answer be represented by G and the Correct answer be represented by C; Such that
G = 2³
C = 2⁹
Divide C by G

From law of indices, 
Applying this law, we have




Multiply both sides by G


Hence, we can conclude that the correct answer is 64 times Geri’s original answer
