Q1 - The equation to solve the problem would be:

→ we apply the exponent rule
→ we use the zero factor principle



The answer is 4, and you can prove it:
The cube of 4 is 64. The double of 8, and 8 squared is also 64.
Q2 - The way of solving the problem would be:
14 - 17 = anwer, becuase the temperature dropped which means the temperature went down.
14 - 17 = -3 degrees
