Answer:
17.21 × 10^7
Step-by-step explanation:
When writting in scientific notation, you only place the decimal as 17.21. Then, you count how many zeros are after of before the numbers. If it's before 17.21, then it would be 17.21^-7, if it is after 17.21, then it would be 17.21^7.
Answer:
[tex]1.721 \cdot 10^{10}[/tex]
Step-by-step explanation:
17,210,000,000 written in scientific notation
To write the number in scientific notation we move the decimal point after the first number.
To move the decimal point after 1, move 10 places to the left
So the number becomes
1.7210000000
Ignore all the zeros. we moved 10 places to the left so multiply with 10^10
[tex]1.721 \cdot 10^{10}[/tex]
