Question

Jim writes down a large number. The number is 543 followed by 12 zeroes. How would Jim express this number in scientific notation? 5.43 × 1014 5.43 × 10-12 5.43E14 5.43 × 1012 5.43E10 5.43 × 1010 5.43E-12 5.43E12

Answer 1

Answer:

5.43 x 10 to the power of 14

Answer 2

Scientific notation is of the form a a \times 10^{b}a×10

b

Number written by Jim = 543000000000000

To find a, take the number and move a decimal place to the right one position.

Number given = 543000000000000

New number = 5.43000000000000

So decimal will be after 5.

Now to find b, count the number of decimals shifted from right to left.

b= 14

So scientific number of 543000000000000 = 5.43 \times 10^{14}5.43×10

14
