Question

(6.25 x 10^9) − (3.44 x 10^8)

Answer 1

To solve this operation we first factorize with the number that has the lowest value in the exponential. In this case:

$\begin{gathered} 6.25\cdot10^9-3.44\cdot10^8 \\ 10^8\cdot(6.25\cdot10^1-3.44) \end{gathered}$

Now, we can multiply the number 6.25 by 10 and solve the operation!

$\begin{gathered} 10^8\cdot(62.5-3.44) \\ 59.06\cdot10^8 \\ 5.906\cdot10^9 \end{gathered}$

Therefore, the answer is 5.906*10^9
