Question

Solve using the correct number of significant digits.
70.4 m x 14 m =
m2

Answer 1

986

if they mark that wrong, the smart alek answer where its correct universally is

`9.85*10^4`

Explanation:

Significant Figures are a pain, however for this one, multiplying its the greatest number of digits.

1 - Solve the equation

70.4 x 14 = 985.6

Because 7 has 3 significant figures the final answer must also, and the most annoying thing about it, is that we have to convert 4 SF's to 3, which is where scientific notation is of use.

9.85 x
`10^(4)`

However because I doubt you were taught this, they probably just want 986 which is the rounded version

Hope this helps,
