What is the average of these two values?
2 x 105 and 6 x 103

414

or

103.5

Step-by-step explanation:

If these are singular values and for example 2 x 105 does not mean two datasets of 105 and 6 x 103 doesnt mean six datasets of 103, then your average would be as follows

((2 x 105) + (6*103)) ÷ 2

The two being how many sets of values you have

This would be solved as follows

((210) + (618)) ÷ 2 =

            (828) ÷ 2 = 414

So in this case it would be 414

However, if the two in 2 x 105 means two data sets of 105;

it would be the same steps of solving but with the ÷ 2 being replaced with ÷ 8 (2 + 6)

((2 x 105) + (6*103)) ÷ 8 =

        ((210) + (618)) ÷ 8 =

                    (828) ÷ 8 = 103.5

Hope this helps.
