The objective lens (right above the slide stage) is 4x. The eyepiece (what you look into) is 10x. 4 times 10 = 40. Whatever the objective lens power is, you have to multiply it by the eyepiece power (usually 10x) to get the overall magnification.
By unit of length and distance and conversion ,we can say that1 cm=10 mm40 cm=400 mm
40 quarts is the same as 10 gallons.
Exactly 40+10+40+10 = 100cm which is its perimeter

40^10 is equal to 10,485,760,000,000,000.

40 x 10^9 = 40,000,000,000 (40 billion).
To solve ( 40 \times 10^2 ), first calculate ( 10^2 ), which equals 100. Then, multiply 40 by 100: ( 40 \times 100 = 4000 ). Thus, the answer is 4000.

In scientific notation, 40 million can be expressed as (4.0 \times 10^7). This format represents the number as a product of a coefficient (4.0) and a power of ten (10 raised to the 7th power).
