Answer : The structure are shown below and the number of stereoisomers are possible in 3,5-dimethylnonane and 3,7-dimethyle-5-ethyldecane are 4 and 8 respectively.

Explanation :

Chiral carbon : It is carbon which is attached to the different types of atoms or molecules.

The number of stereoisomers possible for a compound is related to the number of chiral centers (n) present in it as,

\text{Number of stereoisomers}=2^n

where,

'n' is the number of chiral carbon present in the compound.

The number of chiral carbon present in 3,5-dimethylnonane is, 2 that means n = 2 (carbon-3 and carbon-5)

\text{Number of stereoisomers}=2^n=2^2=4

The number of stereoisomers are possible in 3,5-dimethylnonane is, 4

The number of chiral carbon present in 3,7-dimethyle-5-ethyldecane is, 3 that means n = 3 (carbon-3, carbon-5 and carbon-7)

\text{Number of stereoisomers}=2^n=2^3=8

The number of stereoisomers are possible in 3,7-dimethyle-5-ethyldecane is, 8
