the lincoln monuments weighs about 350,000 pounds. what is this number in scientific notation? 3.5 x 10^6 3.5 x 10^4 3.5 x 10^3 3.5 x 10^5

Explanation:

Step1: Recall scientific - notation form

Scientific notation is \(a\times10^{n}\), where \(1\leqslant a<10\) and \(n\) is an integer.

Step2: Rewrite 350000

To get \(a\) in the range \(1\leqslant a < 10\), we move the decimal point 5 places to the left in 350000. So, \(350000 = 3.5\times10^{5}\).

Answer:

D. \(3.5\times 10^{5}\)
