8.6 x 10^-3
You asked:
Evaluate the expression: \(8.6 \cdot {10}^{-3}\)
MathBot Answer:
\[8.6 \cdot {10}^{-3} = \frac{43}{5000} = 0.0086\]
\[\begin{aligned}8.6 \cdot {10}^{-3}& = \left(8 + \frac{6}{10}\right) \cdot \frac{1}{10^{3}}\\& = \left(8 + \frac{3}{5}\right) \cdot \frac{1}{10^{3}}\\& = \frac{43}{5} \cdot \frac{1}{10^{3}}\\& = \frac{43}{5} \cdot \frac{1}{1000}\\& = \frac{43}{5000}\end{aligned}\]
