11 80 × 1 -81   Final Exponent: 1
Value:
Solution
When you multiply two exponent expressions with the same common base, you can add the exponents.
Final exponent = 80 + -81 = -1
1 80 × 1 -81 = 1-1
1-1 = 1
22 -81 × 2 84   Final Exponent: 2
Value:
Solution
When you multiply two exponent expressions with the same common base, you can add the exponents.
Final exponent = -81 + 84 = 3
2 -81 × 2 84 = 23
23 = 8

### Complexity=5, Mode=divide

Find the final exponent and the value of the expression after the exponent has been evaluated. If the answer is a fraction, express it as 'numerator'/'denominator', i.e. '5/7'

12 -6 ÷ 2 -3   Final Exponent: 2
Value:
Solution
When you divide two exponent expressions with the same common base, you can subtract the exponents.
Final exponent = -6 - -3 = -3
2 -6 ÷ 2 -3 = 2-3
2-3 = 1/8
