That number is already in standard form.

731,934,000

Look at all the digits that are not zero, and place the decimal point in a way that you have a number from 1 to less than 10.

Take 731934, and place the decimal point after the 7 giving 7.31934.

The original decimal point was after the third zero, so now using the original number, count the number of decimal places you moved the decimal point. The decimal point moved 8 places to the left. That means you need an exponent of 8.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
