Question

Use scientific notation to simplify the expression. Give the answer in standard notation

288,000
------------
(12,000)(0.00004)

Answer 1

\[= (2.88\times 10^5)/ ((1.2 \times 10^4)(4.0 \times 10^{-5}))\]
\[= ((2.88\times 10^5)(4.0 \times 10^{5}))/(1.2 \times 10^{4})\]
\[= ((2.88)(4.0)/1.2) \times 10^{6}\]
\[= 0.6 \times 10^{6}\]
\[= 6.0 \times 10^{5}\]
