Q. Which expression is equivalent to 64×1046^4 \times 10^4?\newlineChoices:\newline(A) 1604\frac{1}{60^4}\newline(B) 60860^8\newline(C) 601660^{16}\newline(D) 60460^4
  1. Understand the expression: Understand the given expression.\newlineWe need to find an expression equivalent to 64×1046^4 \times 10^4. This involves two numbers, 66 and 1010, both raised to the power of 44 and then multiplied together.
  2. Use exponent property for multiplication: Use the property of exponents for multiplication.\newlineWhen multiplying two powers with the same exponent but different bases, we can multiply the bases first and then apply the exponent to the result.\newline64×104=(6×10)46^4 \times 10^4 = (6 \times 10)^4
  3. Calculate product of bases: Calculate the product of the bases.\newlineMultiply the bases 66 and 1010 before applying the exponent.\newline6×10=606 \times 10 = 60
  4. Apply exponent to product: Apply the exponent to the product of the bases.\newlineNow that we have the product of the bases, we raise it to the power of 44.\newline(6×10)4=604(6 \times 10)^4 = 60^4
  5. Match with given choices: Match the result with the given choices.\newlineThe expression 60460^4 matches with choice (D) 60460^4.
