Q. Which expression is equivalent to (91)3(9^1)^3?\newlineChoices:\newline(A) 193\frac{1}{9^3}\newline(B) 949^4\newline(C) 194\frac{1}{9^4}\newline(D) 939^3
  1. Exponent Rule Explanation: Understand the exponent rule for powers raised to powers.\newlineWhen we raise a power to another power, we multiply the exponents.\newline(am)n=a(mn)(a^m)^n = a^{(m*n)}
  2. Applying Exponent Rule: Apply the exponent rule to (91)3(9^1)^3.\newlineWe have a power (91)(9^1) being raised to another power (3)(3), so we multiply the exponents.\newline(91)3=913=93(9^1)^3 = 9^{1*3} = 9^3
  3. Finding Equivalent Expression: Choose the equivalent expression for (91)3(9^1)^3. From the calculation in Step 22, we know that (91)3(9^1)^3 is equivalent to 939^3.
