No, 90 is not a square number. 81 is 9 squared and 100 is 10 squared.

The Law of Cosines shows the affect of the angle between vectors. R^2 = (A+B)(A +B)*= (AA* + BB* + 2ABcos(AB)) If the angle is less than 90 degrees the resultant squared R^2 is greater than the sum of the vectors squared. If the angle is 90 degrees the resultant squared is the sum of the vectors squared. If the angle is greater than 90 degrees, the resultant squared is less than the Sum of the vectors squared.

-90 squared is rational - it is +8100. All perfect squares are not only rational but they are integers.

A squared + B squared = C squared And the therem is a right triangle (90 degrees) the long bit is C the bottom is B and the other one is A

3x2-39x-90 = (3x+6)(x-15) when factored

It is: 90 times 90 = 8100

No, 90 is not a square number. 81 is 9 squared and 100 is 10 squared.

The root of 8100 is 90, so yes it is a squared number.

9 squared plus 3 squared is 90.

90 000 metres squared

90 meters squared.

This is the description of the Pythagorean theorem. It applies to any "right" triangle -- that is, a triangle with one angle of exactly 90-degrees, and two other angles that add up to 90-degrees. A = the measurement of the length of one side of the triangle making up the 90-degree angle. B = the measurement of the length of the OTHER side of the triangle making up the 90-degree angle, perpendicular to "A". C = the measurement of the length of the third side of the triangle opposite to the 90-degree angle, also called the hypotenuse In any right triangle, A-squared + B-squared = C-squared

The original number is 10 because: 10 squared = 10+90
