6 x 10^10
5 x 10^-9
0.0000000734 = 7.34 x 10^-8 ≈ 7 x 10^-8
679 is the product of the largest single-digit prime number and the largest two-digit prime number.
There need no be any estimated digit.

3.94 x 10^-6
5 x 10^-9
That would be 3 x 10^14 .

679 is the product of the largest single-digit prime number and the largest two-digit prime number.
The only pair of positive single-digit numbers which give a product of 81 are 9 and 9.
the estimated digit in 0.0782m is?
A single number cannot produce a product.
There need no be any estimated digit.
99, I would say.
