Question

Evaluate the following using
powers of ten rules.
104)1.042

Answer 1

0.0001042

Explanation:

Power of tens rule states that if the denominator of a fraction has the positive power of 10, decimal in the numerator will be shifted to the left by the same number of places as exponent.

10⁴) 1.042 =
`(1.042)/(10^4)`

In the denominator of the given fraction, exponent of 10 = +4

So the decimal in numerator will be shifted left by 4 places.

`(1.042)/(10^4)=0.0001042`

Therefore, answer is 0.0001042
