Multiplication and division with the powers of ten

So, when multiply powers of ten, all you have to do add up the powers.

The reverse goes when you are dividing. You would subtract the powers.

9 x 10^7                    =>   3 x 10^3

The words " how many times as large as " indicates that we are going to divide the two, making it look like this:

\frac{(9)(10^{7}) }{(3)(10^{3}) }

Divide the 9 by 3 you get 3

Then subtract 10^3 from 10^7

Therefore, the answer is 3 x 10^4, or A

Unit conversion is a way of converting some common units into another without changing their real value. The option in which more water will be used is by filling a bathtub.

<h3>Units conversion</h3>

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

Given water flows from a shower at a rate of 0.35 cubic feet per minute. Therefore, the water that will be used in the shower,

Water used in Shower = 0.35 × 15 = 5.25 cubic feets

Water used in bathtub = 0.5 yards³ = 13.5 cubic feets

Hence, the option in which more water will be used is by filling a bathtub.
