Question

Ms. Shin is 158 cm tall. The North Hollywood apartment building is 100 times taller than Ms. Shin. Express the height of the North Hollywood apartment building in scientific notation.

Answer 1

We have the following:

$\begin{gathered} \frac{158}{x}=\frac{1}{100} \\ x=100\cdot158 \\ x=15800 \end{gathered}$

therefore, the north hollywood measure 15800 cm, in the scientific notation would be:

$x=1.58\cdot10^4$
