First, find the number of inches
<span>1225 Miles = 77616000 Inches
then, move the decimal to until you have a ones place. </span>
<span>77616000. the decimal for this number moves to the left SEVEN places.
you end up with 7.7616000
</span>
it will look like this:
7.8 * 10^7
I rounded to the .8 because you didn't state how many significant figures, but it could easily be 7.76 * 10^7
the exponent above the 10 will tell you how many places to move. to get back to your original number, move it back to the right seven places. Of course, you would have to place hold the numbers with 0s. If it were negative, you would move the decimal the opposite way.
The answer is 435,175,000.
Divide by 10 both sides and you get a=4
Answer:
If a and b are two positive rational numbers such that ab is not a perfect square of a rational number, then ab is an irrational number lying between a and b.
So an irrational number between 3 and 4 is=3×4=3×4=3×2=23
