Question

what is 17,210,000,000 written in scientific notation? enter your answer in the box.

Explanation:

Step1: Recall scientific notation form

Scientific notation is in the form \( a \times 10^{n} \), where \( 1 \leq |a| < 10 \) and \( n \) is an integer.

Step2: Determine \( a \) and \( n \) for \( 17,210,000,000 \)

To get \( a \), we move the decimal point to the left until there is one non - zero digit to the left of the decimal point. For \( 17,210,000,000 \), moving the decimal point 10 places to the left gives \( a = 1.721 \). The number of places we moved the decimal point is \( n = 10 \).
So, \( 17,210,000,000=1.721\times 10^{10} \)

Answer:

\( 1.721\times 10^{10} \)
