How do you calculate total magnification on a compound light microscope?

(list them in alphabetical order since I can't do multiple correct options on this)

​ (a)   ​ x ​ ​ (b)   = ​ ​ (c)   ​

• total magnification
• objective lens
• eyepiece
• diaphragm
• nose piece

​ Simon was viewing a specimen on his microscope on low power. What was his total magnification? (list the numbers in ascending order since I can't do multiple correct answers on this type of question)

Show the calculation...

​ (a)   x ​ (b)   = ​ (c)  

• 4
• 10
• 40
• 100

What is the magnification power of the medium power objective lens?

• 4x

• 10x

• 40x

• 100x

What is the magnification power of the low power objective lens?

• 4x

• 10x

• 40x

• 100x

What is the magnification power of the high power objective lens?

• 4x

• 10x

The low power is 5x, medium power is 10x, high power is 20x and the eye piece is 4x. What is the total magnification under medium power?

• 39x

• 14x

• 80x

• 40x

• 9x

If a biologist uses a microscope with an eyepiece of 10x magnification and an objective lens of 5x, what is the total magnification observed?

This photo of yeast was taken through a microscope with a 10x ocular lens and a 100x objective lens. What is the Total Magnification?
