Question

anonymous · Answer

462 is the amount of meters that summits Mt. E.

raden · Answer

4.5x10^-3 x 11 = 49.5 x 10^-3
now, can you evaluate this :
49.5 x 10^-3  -  4.5 x 10^-3 = .... ?

anonymous · Answer

4.5?

anonymous · Answer

no the answer to his equation was my answer. I'm sorry i didnt explain it 


49.5 x 10^-3  -  4.5 x 10^-3 = 462

anonymous · Answer

in other way 
$$\huge\frac{ 49.5 }{ 10^3 } - \frac{ 4.5 }{ 10^3 }$$
you can move base 10 along with the exponent to the denominator, this would change the negative exponent to positive, to make the problem simpler

raden · Answer

what is 49.5 - 4.5 ?
then times 10^-3
