solve (7.1 × 10–15) × (2 × 103)
You asked:
Evaluate the expression: \(\left(7.1 \cdot 10 - 15\right) \cdot 2 \cdot 103\)
MathBot Answer:
\[\left(7.1 \cdot 10 - 15\right) \cdot 2 \cdot 103 = 11536\]
\[\begin{aligned}\left(7.1 \cdot 10 - 15\right) \cdot 2 \cdot 103& = \left(\left(7 + \frac{1}{10}\right) \cdot 10 - 15\right) \cdot 2 \cdot 103\\& = \left(\frac{71}{10} \cdot 10 - 15\right) \cdot 2 \cdot 103\\& = \left(71 - 15\right) \cdot 2 \cdot 103\\& = 56 \cdot 2 \cdot 103\\& = 112 \cdot 103\\& = 11536\end{aligned}\]
