Q. 64273 \sqrt[3]{64^{27}} \newlineWhich of the following is equivalent to the given expression?\newlineChoose 11 answer:\newline(A) 43 4^{3} \newline(B) 643 64^{3} \newline(C) 818 8^{18} \newline(D) 6424 64^{24}
  1. Understand the expression: Understand the given expression 64273 \sqrt[3]{64^{27}} .\newlineThis expression is asking for the cube root of 64 64 raised to the 27th 27th power.
  2. Simplify the base: Simplify the base 6464 to a power of 22.\newlineSince 6464 is 22 raised to the 66th power (262^6), we can rewrite 642764^{27} as (26)27(2^6)^{27}.
  3. Apply power of a power rule: Apply the power of a power rule.\newlineThe power of a power rule states that (am)n=a(mn)(a^m)^n = a^{(m*n)}. Therefore, (26)27(2^6)^{27} becomes 2(627)2^{(6*27)}.
  4. Calculate the exponent: Calculate the exponent.\newlineMultiply the exponents: 6×27=1626 \times 27 = 162. So, 2(6×27)2^{(6 \times 27)} is 21622^{162}.
  5. Apply the cube root: Apply the cube root to the expression.\newlineThe cube root of 21622^{162} is the same as 216232^{\frac{162}{3}} because am3=am3\sqrt[3]{a^m} = a^{\frac{m}{3}}.
  6. Calculate the new exponent: Calculate the new exponent.\newlineDivide the exponent by 33: 1623=54\frac{162}{3} = 54. So, 216232^{\frac{162}{3}} is 2542^{54}.
  7. Determine the correct choice: Determine which answer choice matches 2542^{54}.\newlineWe need to find an answer choice that is equivalent to 2542^{54}. Let's examine the choices:\newline(A) 434^3 is 262^6, which is not equal to 2542^{54}.\newline(B) 64364^3 is (26)3(2^6)^3, which is 2182^{18}, not 2542^{54}.\newline(C) 8188^{18} is 2542^{54}00, which is 2542^{54}, so this is the correct choice.\newline(D) 2542^{54}22 is 2542^{54}33, which is 2542^{54}44, not 2542^{54}.
