The number 5.1×10^7 written in decimal notation is 51,000,000.

To convert a number in scientific notation to decimal notation, we need to move the decimal point to the right or left based on the exponent.

The number 5.1×10^7 means 5.1 multiplied by 10 raised to the power of 7.

To convert it to decimal notation, we move the decimal point 7 places to the right since the exponent is positive.

Starting with 5.1, we move the decimal point seven places to the right, resulting in:

51,000,000

So, the number 5.1×10^7 written in decimal notation is 51,000,000.

To convert the number 5.1×10^7 into decimal notation, you need to multiply 5.1 by 10 raised to the power of 7.

To do this, you can simply move the decimal point 7 places to the right because when you multiply a number by 10 raised to the power of n, you move the decimal point n places to the right.

Starting with 5.1, when you move the decimal point 7 places to the right, you get:

5.1 × 10^7 = 51,000,000

Therefore, 5.1×10^7 written in decimal notation is 51,000,000.
