Considering the data in the question, the focal length of the objective lens that will give a total magnification of 200x is <u>0.8cm focal length.</u>
The whole question is:
You are using a microscope with a 10x eyepiece. What focal length of the objective lens will give a total magnification of 200x? Assume a length L = 160mm.
<h3>How was the answer derived?</h3>
Given that total magnification is 200
And the Assume length is 160
Since we used a microscope with a 10x eyepiece, the magnification would be divided by 10.
=> 200 ÷ 10 = 20.
Also, the focal length is measured in centimeters or meters; we would change the millimeters of focal length to centimeters. Therefore, we have 160 ÷ 10 = 16
The formula for the focal length of the objective lens = assumed length ÷ total magnification.
=> 16 ÷ 20 = 0.8cm.
Hence, in this case, it is concluded that the correct answer is "0.8cm."

The identification of the polynomial expression is as follows:
- Binomial, degree 2
- Trinomial degree 6
- Monomial, degree 4
<h3>What is a polynomial?</h3>
A polynomial shows the relation of more than two algebraic terms and the sum of powers of a polynomial in more than one variable. Polynomials are represented in terms of 
;
where;
- k = any number
- n = positive integer.
The degree of a polynomial expressions can be:
- Monomial
- Binomial
- Trinomial
Let's assume we have the following equation;
- 6b² - 7
- x²y - 9x⁴y²+ 3xy
- 35r³s
Their degree of polynomial expression is:
- Binomial, degree 2
