A scientist measured the mass of a meteorite fragment and found it to be 9.436 grams. which shows a way to represent the value of the 4 in this number?

+ x

Explanation:
We will try to simplify the given expression into terms of ab and then substitute with ab = x as follows:
2a³b + a²b + ab
a² (2ab + ab) + ab
a² (3ab) + ab
a² (3x) + x

Since ab = x, therefore, a = x/b
Substitute with this in the above expression to get:
(x/b)²(3x) + x
+ x

Hope this helps :)
