(1.6x10^12) divided by (8.01x10^23) =?

1.99750312 * 10 ^(-12)

Step-by-step explanation:

When we divide numbers in scientific notation

1.6*10^12

8.01 * 10^23

We divide the numbers out front and subtract the exponents on the powers of 10

(1.6/8.01) * 10^(12-23)

.199750312 * 10^(-11)

But this is not proper scientific notation.  We need 1 number in front of the decimal.  If we move the decimal 1 place to the left, we subtract 1 from the exponent

1.99750312 * 10 ^(-11-1)

1.99750312 * 10 ^(-12)

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
