Question

A river discharges 4 x 106 cubic feet of water into the

Pacific Ocean each second. There are 86,400 seconds in
one day. To find the amount of water discharged each day,
a scientist multiplied 4 x 106 by 86,400 on his calculator.
The display showed:
3456E+14
Explain what 3.456E + 14 means.
OA) 3.456^14
OB) 3.456 *10^6
OC) 3.456 x 10^14
OD) 3.456 x 10^-14

Answer 1

C

Explanation:

Here, we want to know what what the display on the calculator means.

Well, the expression has to do with how scientific calculators display powers of 10.

So what this means is that the value 3.456 is raised to the power of 14.

This is a way in which the screen of the scientific calculators maximizes the space on their screens.

Perhaps, we have the result of a multiplication to the powers of 27. It would be quite funny seeing 27 zeros lying on the screen of the calculator right? isn’t it?

So the calculator makes a better way of this by just printing E 27 and this automatically means 10 raised to the power of 27

This makes our answer C

Kindly note that the + sign indicates that the power of the 10 is positive 14.
