Scientific Notation – Example 1:

Write \(0.00015\) in scientific notation.

Solution:

First, move the decimal point to the right so that you have a number that is between \(1\) and \(10\). Then: \(N=1.5\)
Second, determine how many places the decimal moved in step \(1\) by the power of \(10\).
Then: \(10^{ \ -4} →\) When the decimal is moved to the right, the exponent is negative.
Then: \(0.00015=1.5×10^{ \ -4} \)

Scientific Notation – Example 2:

Write \(9.5 \times 10^{\ -5}\) in standard notation.

Solution:

\(10^{-5} →\) When the decimal is moved to the right, the exponent is negative.
Then: \(9.5×10^{-5}=0.000095\)

Scientific Notation – Example 3:

Write \(0.00012\) in scientific notation.

Solution:

First, move the decimal point to the right so that you have a number that is between \(1\) and \(10\). Then: \(N=1.2\)
Second, determine how many places the decimal moved in step \(1\) by the power of \(10\).
Then: \(10^{-4}→ \) When the decimal is moved to the right, the exponent is negative.
Then: \(0.00012=1.2×10^{-4}\)

Scientific Notation – Example 4:

Write \(8.3×10^{-5}\) in standard notation.

Solution:

\(10^{-5} →\) When the decimal is moved to the right, the exponent is negative.
Then: \(8.3×10^{-5}=0.000083\)
