Answer #1

Scientic notation: a x 10

here, a is in between 1 to 10,i.e, 1<a<19

Here, value of m is number of places you move the decimal point to satify the value of a .

If the number you want to convert in  Scientic notation is between 1 to 0,then value of m is negative otherwise it is positive.

2)

a)0.00000000007461 m = 7.461\times10-11 m ( move 11 places to satisfy value of a)

b) 19746000 mi =1.9746\times107 mi ( move 7 places to satisfy value of a)

3)

a) 4.50\times10-7 cm= 0.000000450 cm

b)1.1258\times107 g= 11258000 g
