Scientific notation is a format in which a number is expressed as a number between 1 and 10 multiplied by a
power of 10.
To convert a number from ordinary to scientific notation, start by moving the decimal point so it is after the
first nonzero digit.
a. To place the decimal point after the first nonzero digit in 46,000,000, move the decimal point 7 places to
the left.
The power of 10 in the number is determined by the movement of the decimal point. Since the decimal point
moved to the left, the exponent on the power of 10 is positive.
Now write 46,000,000 in scientific notation.
46,000,000=4.6x107
b. Use the same procedure to write 0.000000212 in scientific notation.
Move the decimal point 7 places to the right, so that it is after the first nonzero digit in 0.000000212.
The exponent in the power of 10 is negative because the decimal point moved to the right.
Write 0.000000212 in scientific notation.
0.000000212=2.12×107
c. To place the decimal point after the first nonzero digit in 0.050461, move the decimal point 2 places to the
right.
Now write 0.050461 in scientific notation.
0.050461=5.0461 x 10-²
