convert to scientific notation: 0.000243
2.43*10^-4
I am not going to provide any more answers to you, I get the impression you might be answer grazing.
I will be happy to critique your work.
To convert a decimal number to scientific notation, follow these steps:
1. Move the decimal point to the right or left so that there is only one non-zero digit to the left of the decimal point. Count the number of places you moved the decimal point.
In the case of 0.000243, you would move the decimal point 4 places to the right to get 2.43.
2. Write the non-zero digit (in this case, 2.43), then multiply it by 10 raised to the power of the number of places you moved the decimal point.
Since you moved the decimal point 4 places to the right, you would write 2.43 x 10^4.
Combining these steps, 0.000243 in scientific notation is 2.43 x 10^(-4).
