8.89 is a number written in SCIENTIFIC NOTATION, a
number between 1 and 10 times a power of ten; the
8.89 X 104
decimal point moved four places LEFT; the exponent
for the power of 10 is a POSITIVE 4.
Study the following problem on SCIENTIFIC NOTATION, rounded off to 3 significant digits.
.0005966 = _________
Converting a decimal number to SCIENTIFIC NOTATION (a
number between 1 and 10 times a power of ten) is done by
moving the decimal point RIGHT from its position in the
original number to a new position which will be immediately
following the first significant digit, giving you a NEGATIVE
power of 10.
Count the number of places you moved the decimal point to
the RIGHT in the original number to its new position
following the first significant number. This will give you the
proper exponent for your NEGATIVE power of 10.
rounded off to 3
= 5.966 X 104
= 5.97 X 104
Convert this number to SCIENTIFIC NOTATION, rounded off to 3 significant digits.
