Which of the following is a valid formula?*1 point=C7*C8=(C7\C8)=(C7xC8)=AVERAGE(C7*C8)

The valid formula among the options given is =C7*C8.

Here's why:

1. =C7*C8: This is a valid formula in Excel. It multiplies the value in cell C7 with the value in cell C8.

2. =(C7\C8): This is not a valid formula. The backslash is not a recognized mathematical operator in Excel.

3. =(C7xC8): This is not a valid formula. The 'x' is not a recognized mathematical operator in Excel. The correct operator for multiplication is '*'.

4. =AVERAGE(C7*C8): This is not a valid formula. The AVERAGE function in Excel calculates the average of a range of cells, not the result of a multiplication operation. The correct usage would be =AVERAGE(C7:C8) to find the average of the values in cells C7 and C8.
