To write numbers in scientific notation you must do what
To write numbers in scientific notation, you must express the number as the product of a decimal number (greater than or equal to 1 and less than 10) and the appropriate power of 10.
Write the number 290,000,000 in scientific notation.
R. 2.9 x 108
S. 29 x 107
T. 2.9 x 10−8
so the answer is r but how do you work it
To write the number 290,000,000 in scientific notation, we need to express it as the product of a decimal number and the appropriate power of 10.
Starting with 290,000,000, we need to move the decimal point to the left until there is only one non-zero digit to the left of the decimal point. In this case, we can move the decimal point 8 places to the left to get 2.9.
Now we need to determine the appropriate power of 10. Since we moved the decimal point 8 places to the left, we need to multiply 2.9 by 10 raised to the power of 8, which gives us 2.9 x 10^8.
Therefore, the number 290,000,000 can be written in scientific notation as 2.9 x 10^8, which is choice R.
