Q. Which expression is equivalent to 103×4310^3 \times 4^3?\newlineChoices:\newline(A) 1403\frac{1}{40^3}\newline(B) 40640^6\newline(C) 40940^9\newline(D) 40340^3
  1. Calculate Powers: First, calculate 10310^3 and 434^3.\newline103=100010^3 = 1000,\newline43=644^3 = 64.
  2. Multiply Results: Next, multiply the results from the previous step.\newline1000×64=640001000 \times 64 = 64000.
  3. Express as Power of 4040: Now, express 6400064000 as a power of 4040.\newline403=6400040^3 = 64000.
  4. Match with Choices: Finally, match the result with the given choices.\newline6400064000 is 40340^3, which corresponds to choice (D).
