#1#

Given: #49 \ "kg"#.

The order of magnitude of a number #N# is given by the equation:

#N=a*10^b#

where:

#a# is a real number that satisfies the inequality #sqrt(10)/10<a<sqrt(10)#

#b# is the order of magnitude and is an integer

Notice how #49=4.9*10#.

#=4.9*10^1#

So, the order of magnitude will be #bb(1)#.
