Question

state the order of magnihade of following number 6400m​

Answer 1

Answer:

if the radius of the earth is 6400 km then what is the order of the magnitude of the radius of the earth...

answer : 10^7 m is the order of magnitude of the radius of the earth.

explanation : order of magnitude :- it is used scientific notation. if any number X in such a way that X = m × 10^n , where m belongs to  then, 10ⁿ is known as order of magnitude.

here given, earth's radius 6400 km

it can be written as 6400000m [ as we know, 1 km = 1000m]

so, 6400 km = 6400000 m

now, 6400000m = 0.64 × 10^7 m

here you can see √10/10 ≤ 0.64 ≤ √10

so, 10^7m is the order of magnitude.
