Answer:
[tex]1.25\times 10^{11}[/tex]
Step-by-step explanation:
We are asked to write $125 billion in scientific notation.
1 billion equals $1,000,000,000.
[tex]\$125\times 1,000,000,000=\$125,000,000,000[/tex]
To write a number in scientific notation, we need two factors such that one is between 0 and 10 and 2nd is a power of 10.
The first number would be 1.25.
Now, we can see that there are 11 digits after decimal, therefore, we will multiply 1.25 by 10 raised to 11th power as:
[tex]1.25\times 10^{11}[/tex]
Therefore, our required number would be [tex]1.25\times 10^{11}[/tex].
