Write these numbers in scientific notation...
1) 2,000,000
2)0.0000007
1. 2*10^6.
2. 7*10^-7.
Sure! I can help you write these numbers in scientific notation.
1) To write the number 2,000,000 in scientific notation, we 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, when we remove all the trailing zeros, we get 2. Since we moved the decimal point 6 places to the left, we multiply 2 by 10^6. Therefore, 2,000,000 in scientific notation is 2 x 10^6.
2) To write the number 0.0000007 in scientific notation, we 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, when we remove all the trailing zeros, we get 7. Since we moved the decimal point 7 places to the right, we divide 7 by 10^7. Therefore, 0.0000007 in scientific notation is 7 x 10^-7.
Remember, in scientific notation, the base (which is always 10) is raised to an exponent that represents the number of places the decimal point was moved. If the decimal point moves to the left, the exponent is positive, and if it moves to the right, the exponent is negative.
