It stands for the magnifying unit.
maybe its a multiplication .
200x and 860x
x to the n divided by x to the n is 1. By the law of powers x to the power n divided by x to the power n is x to the power (n minus n), ie x to the power zero. Things which are equal to the same thing are equal to each other. Therefore x to the power zero = 1. (Unless x = zero!)
5^3 = 5 x 5 x 5
3 to the third power = 3 x 3 x 3
maybe its a multiplication .
power
lower power= 20 x 10= 200x higher power= 20 x 43= 860x
10 x * 40x = 400x
Multiply the magnification or power of the objective lens times the power of the eyepiece and it equals the total magnification
200x and 860x
magnification of the eyepiece X magnification of the lens (depends on which one you choose)
x to the power a divided by x to the power b is x to the power (a - b) When a and b are equal then this is x to the power a divided by x to the power a, ie 1. x to the power (a - a) = x to the power zero. Things which are equal to the same thing are equal to each other, so 1 = x to the power zero.
no
Not at all as both times the biologist is using the "X" lens.
SEM, scanning electron microscope
103 = 10 x 10 x 10
