10>9

To express the number 8,058,044,651 in scientific notation, we need to move the decimal point to after the first nonzero digit and multiply it by a power of 10.

In this case, the first nonzero digit is 8, so we can write 8,058,044,651 as 8.058044651 × 10^9 in scientific notation.

In expanded form, 8,058,044,651 can be written as:

8 × 1,000,000,000 + 0 × 100,000,000 + 5 × 10,000,000 + 8 × 1,000,000 + 0 × 100,000 + 4 × 10,000 + 4 × 1,000 + 6 × 100 + 5 × 10 + 1 × 1

To express the number 8,058,044,651 in scientific notation, we need to move the decimal point to the right until there is only one non-zero digit to its left.

Starting from 8,058,044,651, we can move the decimal point four places to the left to get 8.058044651.

Next, we count the total number of places we moved the decimal point, which is four. Since we moved the decimal point to the left, the exponent of 10 will be positive.

Therefore, the number 8,058,044,651 can be expressed in scientific notation as 8.058044651 x 10^4.

In expanded form, we can write it as 80,580,446,510.
