Q. Select all the expressions that are equivalent to 64×686^4 \times 6^8.\newlineMulti-select Choices:\newline(A) 1632\frac{1}{6^{32}}\newline(B) 6126^{12}\newline(C) 6326^{32}\newline(D) 1612\frac{1}{6^{-12}}
  1. Combine Exponents: Use the property of exponents that states am×an=am+na^m \times a^n = a^{m+n} to combine 646^4 and 686^8.\newlineCalculation: 64×68=64+8=6126^4 \times 6^8 = 6^{4+8} = 6^{12}
  2. Check Options: Check each of the given options to see if they are equivalent to 6126^{12}.\newlineOption (A) 1/6321/6^{32} is not equivalent because it represents the reciprocal of 6326^{32}, not 6126^{12}.
  3. Option (A): Option (B) 6126^{12} is equivalent because it matches the result from Step 11.
  4. Option (B): Option (C) 6326^{32} is not equivalent because it represents 66 raised to the power of 3232, which is not the sum of 44 and 88.
  5. Option (C): Option (D) 1/6121/6^{-12} is equivalent because using the property of negative exponents an=1/ana^{-n} = 1/a^n, it simplifies to 6126^{12}.\newlineCalculation: 1/612=6121/6^{-12} = 6^{12}
