Sergio is asked to write one million in scientific notation. he writes 10^6 and gets it wrong. why was he wrong? he should have written 10 5 . he should have written 1 × 10 5 . he should have written 10 6 . he should have written 1 × 10 6 .

Step-by-step explanation:

One million = 1000,000

In Scientific notation we express a long number or a very small number convenient in decimal format followed by a product of 10 raised to some power depending upon the small whether it is very big or very small. If it is big power of ten is positive and if it is small and less than 1 , the power of 10 is negative.

100000 can be written as 1 x 1000000

1000000=10^6

1000000= 1 x 10^6

While Sergio wrote only 10^6 he missed to write the product with 1 i.e. 1x 10^6. That was why he was wrong.

80 the answer is 80
