Write 2.09 x 10^5 in decimal notation. show work
2.09 x 10^5 can be written in decimal notation as 209,000.
To convert from scientific notation to decimal notation, you move the decimal point to the right or left depending on the exponent. In this case, since the exponent is positive (5), you move the decimal point five places to the right.
So, when you move the decimal point of 2.09 five places to the right, you get 209000, which is the decimal notation for 2.09 x 10^5.
To write 2.09 x 10^5 in decimal notation, we need to multiply the coefficient (2.09) by the power of 10 (10^5).
2.09 x 10^5 = 2.09 * (10 * 10 * 10 * 10 * 10)
Simplifying this expression, we get:
2.09 x 10^5 = 2.09 * 100000
Finally, multiplying 2.09 by 100000:
2.09 x 10^5 = 209000.
To write 2.09 x 10^5 in decimal notation, we can start by expanding the exponent term. The exponent 5 indicates that we need to move the decimal point 5 places to the right.
So, we start with 2.09 and move the decimal point five places to the right:
2.09 x 10^5 = 209,000
Therefore, 2.09 x 10^5 in decimal notation is equal to 209,000.
