The distance from the Earth to the sun is 93,000,000 miles. Write this number in scientific notation.
If you move the decimal place to the left, the exponent is positive. If you move decimal place to the right, exponent is negative.
9.3 * 10^7
To write the number 93,000,000 in scientific notation, we need to express it as a product of a number between 1 and 10 and a power of 10.
First, we observe that 93,000,000 can be written as 9.3 multiplied by 10,000,000.
In scientific notation, we write the number 9.3 as 9.3 × 10^1 because it can be expressed as 9.3 multiplied by 10 raised to the power of 1.
Therefore, the distance from the Earth to the sun, 93,000,000 miles, can be written in scientific notation as 9.3 × 10^7.
To write the number 93,000,000 in scientific notation, you need to move the decimal point so that there is only one non-zero digit to the left of the decimal point.
In this case, we can achieve this by moving the decimal point seven positions to the left.
So the number 93,000,000 in scientific notation is written as 9.3 x 10^7.
