it's impossible to just use the eyepiece without an objective lens, but the eyepiece alone is 10x.

The maximum magnification without use the oil?
It is of 45x objective and 10x of eyepiece total 450x
What is the objective power if a 10X eyepiece produces a total magnification of 100X?
Using a 10X eyepiece, a student would need to use a 10X objective to have a final 100X magnification. 10 X 10 = 100X
How do you find the total magnifying power of a microscope?
MP=(d/L)*(1-(L-l)f) where d would be the distance from the eye to the image without a lens L is the distance from the eye to the new virtual image (with a lens) l is the distance from the eye to the lens this equation only covers a single lens (whereas there tend to be two in a microscope), but that's no worry; use it twice! (i.e treat both lenses as independent sources of the image)
What is the magnification of a microscope with a 10x ocular and a 95x oil-immersion objective?
950
What is the focal length of a telescope's mirror if I use an eyepiece with a focal length of 26 mm and I get a magnification of 70x?
1.82 meters
How can you work out magnification when using a microscope?
Well, its easy. Its Image lenght over Object lenght. In other words,you divide the lenght of your diagram with the lenght of the real object being drawen. If the answer is not up to one, then your diagram is smaller than the real one.
High power on microscope?
On a the microscope I use, the ocular (eyepiece) has a magnification power of 10x. The 'low' (or 'scanning') objective lens is 4x, the 'medium' has a power of 10x, and the 'high' has a power of 40x. Multiply the ocular by the lens you're using to get your 'total magnification.' TIP: Only use the coarse adjustment knob while on 'low' power, then use the fine adjustment. Why? If you use the coarse adjustment knob on 'medium' or 'high,' there's a good chance you'll crack your slide. -BugCrunch
The magnification of a telescope is changed by changing the?
The magnification of a telescope is the ratio of the effective focal length of the objective to the focal length of the eyepiece. For example, a small telescope's objective may have a focal length of 800mm. When an eyepiece with a focal length of 25mm is used, the magnification is 800/25 = 32. The term "effective focal length" refers to the focal length of the objective as affected by any "focal extender". Many telescopes are designed to have a short total size, but high power, by "folding" the optical path. A mirror-type objective with a focal length of perhaps 800mm is coupled with a smaller curved mirror that intercepts the last 200mm and extends it to 800mm, a 4x extension, so that the effective focal length of that objective is 3200mm. Use that with a 25mm eyepiece and the magnification is 3200/25 = 128. By the way, if a telescope is smaller than you are, it is seldom much use to view using a magnification greater than 50 to 100. Most objects are best viewed at relatively low powers such as 30 or so.
Low power magnification is best for scanning objects under the microscope?
Yes. 4x - low power magnification is best for scanning objects under a microscope. Why? I honestly don't know but will guess; medium and high power are based off the setting of low power - you don't use coarse adjustment knob for medium and high only fine detail because the coarse is already adjusteded from low.

A total magnification of 100x requires the use of the 10x ocular lens with which objective?
10X
How is macroscopic magnification computed?
The eye piece provides x10 magnification, and times it by the low power objective. (Smallest tube) So, if the low power objective was x10, and the eye piece being 10, then the magnification would be x100 Use this for other objectives too.
