Final answer:

None of the provided options (a) =SUM(A1:A3)*SUM(B1:B3), (b), (c), or (d) =A1:A3+B1:B3 is equivalent to the =SUMPRODUCT(A1:A3,B1:B3) Excel formula. The SUMPRODUCT formula calculates the sum of products of corresponding elements, which is not achieved by any of the given alternatives.

Step-by-step explanation:

The formula =SUMPRODUCT(A1:A3,B1:B3) calculates the sum of the products of corresponding elements in the two arrays or ranges A1:A3 and B1:B3. In other words, if A1:A3 contains a1, a2, a3 and B1:B3 contains b1, b2, b3, SUMPRODUCT performs the operation (a1*b1) + (a2*b2) + (a3*b3). Therefore, the equivalent formulae would need to reflect this element-wise multiplication followed by summing the results.

Looking at the provided options:

  • Option a) =SUM(A1:A3)*SUM(B1:B3) calculates the sum of each range independently and then multiplies those sums together, which is not the same as SUMPRODUCT.
  • Option b) and option c) are not proper Excel formulas and would result in an error.
  • Option d) =A1:A3+B1:B3 would simply add corresponding elements without multiplying them, which is also different from what SUMPRODUCT does.

Therefore, none of the provided options are equivalent to the =SUMPRODUCT(A1:A3, B1:B3) formula.
