question
if the number $7.5 \times 10^{10}$ is written in standard notation, it is the number 75 followed by how many zeroes?
select the correct answer below:
11 zeroes
9 zeroes
8 zeroes
7 zeroes
10 zeroes

Explanation:

Step1: Convert scientific notation to standard form

The scientific notation \(a\times10^{n}\) (where \(1\leqslant a<10\)) is converted to standard form by moving the decimal point \(n\) places. For \(7.5\times 10^{10}\), we move the decimal point 10 places to the right.
\(7.5\times10^{10}=75000000000\)

Step2: Count the number of zeros after 75

The number \(75000000000\) has 9 zeros after 75.

Answer:

9 zeroes
