Write five numbers that are at least 8 digits long under standard form write the expanded form and the word form for each number under the appropriate heading

Part A

Standard form

The following numbers are written in standard form

a.) 34,000,000 = 3.4 x 10^7

b.) 321,231,780 = 3.2123178 x 10^8

c.) 1,688,768,127 = 1.688768127 x 10^9

d.) 37,200,000 = 3.72 x 10^7

e.) 375,574,146 = 3.75574146 x 10^8

Part B:

Expanded form

The numbers above, written in expanded form are as follows:

a.) 34,000,000 = 30,000,000 + 4,000,000

b.) 321,231,780 = 300,000,000 + 20,000,000 + 1,000,000 + 200,000 + 30,000 + 1,000 + 700 + 80

c.) 1,688,768,127 = 1,000,000,000 + 600,000,000 + 80,000,000 + 8,000,000 + 700,000 + 60,000 + 8,000 + 100 + 20 + 7

d.) 37,200,000 = 30,000,000 + 7,000,000 + 200,000

e.) 375,574,146 = 300,000,000 + 70,000,000 + 5,000,000 + 500,000 + 70,000 + 4,000 + 100 + 40 + 6

Part C:

Word form

The numbers above, written in word form are as follows:

a.) 34,000,000 = thirty four million

b.) 321,231,780 = three hundred and twenty one million, two hundred and thirty one thousand, seven hundred and eighty

c.) 1,688,768,127 = one billion, six hundred and eighty eight million, seven hundred and sixty eight thousand, one hundred and twenty seven

d.) 37,200,000 = thirty seven million, two hundred thousand

e.) 375,574,146 = three hundred and seventy five million, five hundred and seventy four thousand, one hundred and fourty six

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.
