Q. Select the equivalent expression.(33⋅66)−3=?Choose 1 answer:(A) 39⋅6181(B) 39618(C) 61839
Understand Problem: Understand the problem and apply the power of a product rule.The problem asks us to find an equivalent expression for (33⋅66)−3. According to the power of a product rule, (ab)n=an⋅bn, we can apply the negative exponent to both terms inside the parentheses.
Apply Product Rule: Apply the negative exponent to both 33 and 66.(33∗66)(−3)=(33)(−3)∗(66)(−3)
Apply Negative Exponent: Simplify the expression using the power of a power rule.According to the power of a power rule, (am)n=am∗n, we multiply the exponents.(33)−3×(66)−3=33∗(−3)×66∗(−3)
Simplify Expression: Perform the multiplication of the exponents. 33∗(−3)×66∗(−3)=3−9×6−18
Perform Exponent Multiplication: Convert the negative exponents to positive exponents by taking the reciprocal.According to the negative exponent rule, a−n=an1, we can rewrite the expression with positive exponents in the denominator.3−9×6−18=391×6181
Convert Negative Exponents: Combine the fractions.Since we are multiplying fractions, we multiply the numerators and the denominators separately.391×6181=39×6181
Combine Fractions: Identify the correct answer from the given options.The expression we have found is 39×6181, which matches option (A).
