Q. Which expression is equivalent to 52×545^2 \times 5^4?\newlineChoices:\newline(A) 565^6\newline(B) 156\frac{1}{5^6}\newline(C) 585^8\newline(D) 158\frac{1}{5^8}
  1. Identify Operation: Identify the operation to perform with the exponents.\newlineWhen multiplying powers with the same base, we add the exponents.\newlineam×an=a(m+n)a^m \times a^n = a^{(m + n)}
  2. Add Exponents: Add the exponents of the powers of 55.52×54=5(2+4)=565^2 \times 5^4 = 5^{(2+4)} = 5^6
  3. Choose Equivalent Expression: Choose the equivalent expression for 52×545^2 \times 5^4 from the given choices.\newline52×545^2 \times 5^4 is equivalent to 565^6, which corresponds to choice (A)56(A)5^6.
