15 = 1252 + 20(1*5) = 125 + 100 = 225
or
15*15 = 15*10 + 10*15/2 = 150 + 75 = 225
No, 15 is not a perfect square.
225 is a perfect squarebecause 225 = 15*15
225
15
The next perfect square after 196 is 225. This is because 196 is the square of 14 (14 x 14), and the next integer is 15. Squaring 15 gives 15 x 15 = 225.
No, because 15 is not a perfect square. The closest perfect square is 16, whose square root is 4.
Yes, it won't be exact, but you can round the number to get a close estimate.
I would use a calculator, since I know that 1525 is not a perfect square. sqrt(1525) = 39.05 (approx).
16,25,36......that`s all :))
The square root of 60 is also equal to the square root of 15x4 the square root of 4 is 2, and 15 is not a perfect square, so the answer is (square root of 15) x 2
To find a number that is both a perfect square and a perfect cube, we must solve x2 = x3 over x ∈Z+. The only two solutions to this equation are 0 and 1, or x = {0,1}. Therefore, zero and one are the only two numbers that are both perfect squares and perfect cubes. --In easier terms: a perfect square is a number that can be "square rooted" and have no remainder. Like, 144. The square root is 12 therefore 144 is a perfect square. A perfect Cube is the same except that it must be "cubed rooted". Like 27. The cube root of this number is 3 therefore 27 is a perfect cube.
200 is not a perfect square. Its square root is a fraction and the square root of a perfect square is always an integer.
