can some one please check if my answer is correct.

Write the number in scientific notation.
15)0.000 294

Answer: 2.94x10^(-4)

looks ok to me.

Thanks Dr.Bob :)

To check if your answer is correct, we can compare it to the correct method of converting a number to scientific notation.

To convert a number to scientific notation, follow these steps:

1. Start by moving the decimal point in the original number to the right or left until there is only one nonzero digit to the left of the decimal point. Count the number of places you moved the decimal point. If the original number is less than 1, move it to the right. If the original number is greater than or equal to 10, move it to the left.

In this case, the original number is 0.000294, which is less than 1. We need to move the decimal point to the right to have one nonzero digit to the left of the decimal point.

2. Write the number you moved the decimal point as a decimal coefficient between 1 and 10.

In this case, the decimal point was moved four places to the right, so the coefficient is 2.94.

3. Finally, write the power of 10 using the number of places you moved the decimal point and the direction in which you moved it.

In this case, we moved the decimal point four places to the right, so the power of 10 would be -4.

Combining the coefficient and the power of 10, we get 2.94 x 10^(-4), which matches your answer.

Therefore, your answer of 2.94 x 10^(-4) is correct!
