Exponential form for 0.0000561
The exponential form of 0.0000561 is 5.61 x 10^-5.
To write the number 0.0000561 in exponential form, you need to move the decimal point to the right until there is only one non-zero digit to the left of the decimal point. In this case, you need to move the decimal point 5 places to the right.
So, 0.0000561 can be written in exponential form as 5.61 x 10^(-5).
To write 0.0000561 in exponential form, you need to express it as a number between 1 and 10, multiplied by a power of 10. Here's how you can do it:
1. Count the number of decimal places between the first non-zero digit (5 in this case) and the decimal point. In this case, there are 5 decimal places.
2. Rewrite the number by moving the decimal point 5 places to the right. This gives you 561.
3. To express it as a number between 1 and 10, divide 561 by 1000 (since there were 3 zeros after the decimal point). This gives you 0.561.
4. Finally, multiply 0.561 by 10 raised to the power of the number of decimal places (5 in this case). This gives you the exponential form of 5.61 x 10^(-5).
So, the exponential form for 0.0000561 is 5.61 x 10^(-5).
