----------
Scientific numbers are a product of a number between 0 and 10 and some power
of 10.
Move you decimal point ten places to the right to get 1.6
If you multiplied that by 10^-10 you would have your original number.
So your number in scientific notation is 1.6 x 10^-10

You need to move the decimal point to the right until
you get 1.6
Each time you move it one place to the right, you are
actually multiplying the number by 10, so every
time you do this, you've got to multiply by 1%2F10
to cancel the effect
.00000000016+=+.0000000016+%2A+10%5E-1
.00000000016+=+.000000016+%2A+10%5E-2
.00000000016+=+.00000016+%2A+10%5E-3
.00000000016+=+.0000016+%2A+10%5E-4
.00000000016+=+.000016+%2A+10%5E-5
.00000000016+=+.00016+%2A+10%5E-6
.00000000016+=+.0016+%2A+10%5E-7
.00000000016+=+.016+%2A+10%5E-8
.00000000016+=+.16+%2A+10%5E-9
.00000000016+=+1.6+%2A+10%5E-10 answer
All these answers are equal to the given number, but
the one you want is the last one because scientific
notation uses one number to the left of the decimal
point times 10 to whatever exponent gives
you the number you want
