Explanation:
In multiplications or divisions, the result must be written using a number of significant figures equal to the smallest number of significant figures contained in the original numbers.
For instance, in this case the two numbers are:
3278 --> 4 significant figures
42 --> 2 significant figures
So, the product must be written using 2 significant figures.
Calculating the product, we get:

Therefore, using 2 significant figures only, the result is

The acceleration of gravity on Mars is about 3.7 m/s². (b)
So anything located on the surface of Mars weighs about 38% of what it would weigh if it were on Earth.
