Sure, let's simplify the given measurement step by step.
We start with the measurement:
[tex]\[ 9.9 \, g \cdot cm^2 \cdot g \cdot cm \][/tex]
First, let's rearrange the terms to group like units together:
[tex]\[ 9.9 \, (g \cdot g) \cdot (cm^2 \cdot cm) \][/tex]
We then combine the like terms:
[tex]\[ 9.9 \, g^2 \cdot cm^{2+1} \][/tex]
Thus, we get:
[tex]\[ 9.9 \, g^2 \cdot cm^3 \][/tex]
So, the simplified unit of the measurement is:
[tex]\[ 9.9 \, g^2 \cdot cm^3 \][/tex]
Hence, the measurement rewritten with a simpler unit is:
[tex]\[ 9.9 \, g^2 \cdot cm^3 \][/tex]
