Well 6^2 = 36 and (8-4)^2 = 16 so you would do 16 + 7 which is 23 and then 36 - 23 = 13.

The length of the insect in the final image is \boxed{9.5\text{ centimeter}}.

Further explanation:

In the question it is given that if an object is viewed under a microscope then the object appears 100 times large than its original size.

It is given that the length of a insect is 0.095 centimeter.

This question is based on the concept of multiplication of decimals.

Consider the length of the insect as x\text{ cm}.

Since, the length of insect is 0.095 centimeter so, trhe value of x is 0.095.

As per the question the size of the final image is 100 times large as the original size so, the size of final image is calculated as follows:

\boxed{S=x\times 100}

Substitute 0.095 for x in the above equation.

\boxed{\begin{aligned}S&=x\times 100\\&=0.095\times 100\\&=9.5\end{aligned}}

From the above calculation it is concluded that the length of the insect in the final image is 9.5\text{ centimeter}.

Therefore, the length of the insect in the final image is \boxed{9.5\text{ centimeter}}.
