4*10^4+ 2*10^3
You asked:
Evaluate the expression: \(4 \cdot {10}^{4} + 2 \cdot {10}^{3}\)
MathBot Answer:
\[4 \cdot {10}^{4} + 2 \cdot {10}^{3} = 42000\]
\[\begin{aligned}4 \cdot {10}^{4} + 2 \cdot {10}^{3}& = 4 \cdot 10^{4} + 2 \cdot 10^{3}\\& = 4 \cdot 10000 + 2 \cdot 10^{3}\\& = 40000 + 2 \cdot 10^{3}\\& = 40000 + 2 \cdot 1000\\& = 40000 + 2000\\& = 42000\end{aligned}\]
