what is 5.1 x 10^7 written in decimal notation
The decimal notation for 5.1 x 10^7 is 51,000,000.
To write 5.1 x 10^7 in decimal notation, you need to move the decimal point 7 places to the right since the exponent 7 indicates the number of zeros to add.
Starting with the number 5.1, you will move the decimal point 7 places to the right, filling in any empty spaces with zeros, to get:
51,000,000
Therefore, 5.1 x 10^7 in decimal notation is 51,000,000.
To convert a number written in scientific notation (with the form a x 10^b) to decimal notation, you multiply the coefficient (a) by 10 raised to the power of the exponent (b).
In this case, we have 5.1 x 10^7. To convert it to decimal notation, we multiply 5.1 by 10 raised to the power of 7:
5.1 x 10^7 = 5.1 * 10,000,000
To perform this multiplication, simply move the decimal point of 5.1 seven places to the right:
5.1 * 10,000,000 = 51,000,000
Therefore, 5.1 x 10^7 is equivalent to 51,000,000 in decimal notation.
