SUMMARY

The discussion focuses on calculating the number of integers between the square roots of 19 and 90. It establishes that √19 is approximately 4.3589 and √90 is approximately 9.4868. By subtracting these two values, the result is 5.1279. Applying the "floor" function to this result yields 5, indicating there are five integers between these two square roots.

How many integers are there between √19 and √90
 
Mathematics news on Phys.org
$4\lt\sqrt{19}\lt5$ and $9\lt\sqrt{90}\lt10$
 
Subtract the lower number from the higher number.

√90 - √19 = 5.1279

Then use the "floor" function on 5.1279. If you are unfamiliar, floor(x) = the greatest integer <= x. (Basically round down)

So the number of integers between these two values is floor(5.1279)=5.
