2.5*10^4 + 3*10^5 is
You asked:
Evaluate the expression: \(2.5 \cdot {10}^{4} + 3 \cdot {10}^{5}\)
MathBot Answer:
\[2.5 \cdot {10}^{4} + 3 \cdot {10}^{5} = 325000\]
\[\begin{aligned}2.5 \cdot {10}^{4} + 3 \cdot {10}^{5}& = \left(2 + \frac{5}{10}\right) \cdot 10^{4} + 3 \cdot 10^{5}\\& = \left(2 + \frac{1}{2}\right) \cdot 10^{4} + 3 \cdot 10^{5}\\& = \frac{5}{2} \cdot 10^{4} + 3 \cdot 10^{5}\\& = \frac{5}{2} \cdot 10000 + 3 \cdot 10^{5}\\& = 25000 + 3 \cdot 10^{5}\\& = 25000 + 3 \cdot 100000\\& = 25000 + 300000\\& = 325000\end{aligned}\]
