1600 (square of 40)
A perfect square Four 90 degree angles and four equal sides
An infinite number of ways. Cut along a line from anywhere on a side to the centre of the square. Make three more cuts, at 90, 180 and 270 degrees to the first at the centre. Each point on a side of the square will give rise to a different set of four identical pieces of the square. And there are an infinite number of points on the side of the square. So an infinite number of answers to the question.
All quadrilateral have four angles. It is possible that all four angles are right angles, even if the quadrilateral is not a square (this would be a rectangle).
4,624 = 682
The number is 9376.
For a number to be a perfect square and a perfect cube, it must be a perfect sixth power. Now 36 = 729 is too small and 56 = 15625 is too large, leaving 46 = 4096 as the answer.
Every square of a 4 digit number has more than four digits.
There are no four-digit perfect squares that are palindromes.
It is the smallest composite number that is both a perfect square and a perfect cube.
No. to be a perfect square, you have to be able to square root it and get a whole number (NOT a decimal) the square root of 3 is 1.732. (1.7322 = 3) a perfect square is a number like 4 the square root of four is 2 (22 = 4)
32 is the smallest two-digit number that can be multiplied by itself to give a four-digit number. (32x32)=1024
It is already a four-digit number.
Lowest four-digit number: 1000 Highest four-digit number: 9999
