#ProblemCorrect AnswerYour Answer
13 -2 × 3 1   Final Exponent: 3
  Value:
Solution
When you multiply two exponent expressions with the same common base, you can add the exponents.
Final exponent = -2 + 1 = -1
3 -2 × 3 1 = 3-1
3-1 = 1/3
#ProblemCorrect AnswerYour Answer
24 72 × 4 -74   Final Exponent: 4
  Value:
Solution
When you multiply two exponent expressions with the same common base, you can add the exponents.
Final exponent = 72 + -74 = -2
4 72 × 4 -74 = 4-2
4-2 = 1/16

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'
#ProblemCorrect AnswerYour Answer
15 -76 ÷ 5 -76   Final Exponent: 5
  Value:
Solution
When you divide two exponent expressions with the same common base, you can subtract the exponents.
Final exponent = -76 - -76 = 0
5 -76 ÷ 5 -76 = 50
50 = 1

21 72 ÷ 1 75   Final Exponent: 1
  Value:
Solution
When you divide two exponent expressions with the same common base, you can subtract the exponents.
Final exponent = 72 - 75 = -3
1 72 ÷ 1 75 = 1-3
1-3 = 1
