Question

Write the order of magnitude of the following measurements a) 25710000 m & b) 0.00000521 kg

Answer 1

Answer:

a. Order of magnitude is 7

b. Order of magnitude is -5

Explanation:

The following measurement can be written in the exponential way in that way it will be more intuitive and understandable.

a. 25710000 m = 2.571 *10 ^7

Here the order of magnitude is 7.

b. 0.00000521 kg = 0.521*(10^-5)

Here the order of magnitude is -5.

Answer 2

Answer:

(a)25710000 = $2.571 * 10^7$ order of magnitude = $10^7$

(b)0.00000521 = $5.21 * 10^{-6}$ order of magnitude = $10^{-6}$

Explanation:

Order of magnitude is usually written as 10 to the nth power. The n represents the order of magnitude. If you raise a number by one order of magnitude, you are basically multiplying that number by 10. If you decrease a number by one order of magnitude, you are basically multiplying that number by 0.1.
