What is the greatest perfect square?
99801 is the greatest 5 digit number * * * * * 99801 is not a perfect square! Sqrt(99801) = 315.91 (approx). The largest 5 digit perfect square is 99856 = 3162
What is the second largest whole number which is a perfect square a perfect cube and a perfect fifth power?
The second LARGEST? Is that correct? I think the second SMALLEST is a much more sensible question. How could you possibly know which is the LARGEST, much less the second largest? The SMALLEST is of course 1. Since 1^2 = 1, 1^3 = 1 and 1^5 = 1. The second SMALLEST I could find is 1073741824. I didn't try all possible numbers, but that was the second smallest I could find. 1024^2 = 1073741824, 32768^3 = 1073741824 and 64^5 = 1073741824. My initial gut was 64, but it isn't a perfect 5th, 2^5 = 32 NOT 64. Just try a couple 5th powers and see which are factorable (into a perfect square and a perfect cube). If you have a graphing calculator (or a computer) you can use the 3rd root and square root functions to do the math for you. But 64^5 was the smallest I could find (other than 1). Other numbers like 12^5, 24^5 and 32^5 did not work-out but 64 did. Hope this helps!
What numbers are perfect cubes?
any number multiplied by itself three times is a cube number eg. 3 x 3 x 3 =27 5 x 5 x 5 =125 so 27 is a cube number, so is 125 you can work out if something is a cube number by cube rooting it there is a cube root button on most scientific calculators
What is the volume of a cube if the edge is 5?
the volume of a cube if the edge is 5=5x5x5 or 125.
What is the volume of a cube with an edge of 5 centimeters?
The volume of a cube with an edge of 5 centimeters is: 125 cm3
