One relationship is that the sum of the nth and the previous triangular numbers is equal to the nth square number.That isT(n-1) + T(n) = S(n)where T(n) is the nth triangular number and S(n) is the nth square number.

Thre are infinitely many solutions. The smalest set with two different triangular number adding to another is 6 + 15 = 21

Two equal numbers mutiplied is the square root of that number. The answer is 14.002856.

In Mathematics, a square number is an integer that is the square of another integer. It is equal to a positive whole number multiplied by itself. For example, 9 is a square number because it is equal to 3x3.

yes

The product of two negative numbers is a positive number. Ergo, the product of the square of a number is equal to the square of its negative equivalent.

A square pyramid has a base with 4 equal sides and triangular faces.

2 and 2

A pyramid with a square base, like the great pyramids of Egypt or Mexico. The bottom is square and they have four equal and identical triangular sides. This makes them different from a tetrahedron, a pyramid with a triangular base and three triangular sides.

28 and 15

Every positive integer has two square roots, a positive square root and a negative square root. This is because, just like a positive number multiplied by a positive number is equal to a positive number, a negative number multiplied by a negative number is equal to a positive number. Therefore, rounded to two decimal places, the positive square root is equal to 7.28, and the negative square root is -7.28.

No No, forty is not a square number. No numbers times itself equal forty. Some Square numbers close to forty are 36 ( 6x6) and 49 (7x7). Hope this helpedType your answer here...

The tenth triangular number is equal to (10 x 11) / 2 = 55.

The sixteenth triangular number is equal to (16 x 17)/2 = 136

Basically a perfect square is a number like 81 or 100. When these numbers are square rooted, they equal whole numbers like 9 or 10. An imperfect square is a number that when is square rooted equals and repeating decimal, like 29 when square rooted equals 5.385164807134504... (Note: Both even and odd number can be imperfect or perfect squares.)

Factors come in pairs. It is only in the case of a square number that the two middle factors are equal and so are counted only once.

They can, but they are called imaginary numbers. This is because a "square" of something is the number that, when multiplied by itself, will equal the first number. A negative multiplied by a negative equals a positive, and positives can't turn into negatives on their own, so there are no square roots of negative numbers.

The formula for the nth triangular number is n(n+1)/2. Therefore, the fourth triangular number is equal to 4 x (4+1) / 2 = (4 x 5) / 2 = 10. The fiftieth triangular number is equal to 50 x (50+1) / 2 = (50 x 51) / 2 = 1275.

Expressed as a sum of square numbers, 29 is equal to Â±52 + Â±22

No, any 2 negative numbers multiplied together equal a positive number

The square root of any non-square number is always irrational, so there is no way to use numbers (other than square roots, surds and squares) to show it precisely.

A pyramid does not need to have any equal sides. A REGULAR pyramid has as many equal sides as the number of sides on the base. So, a triangular pyramid (tetrahedron) will have 3 equal faces, a square based pyramid will have 4, etc.

A square number is the product of a number multiplied by itself. It is square because both numbers are equal, just like the sides of a square. Example: 3x3=9 the square root of 9 is 3.

There is no simple answer because there is no known pattern to prime numbers. You could try dividing the each number by all the prime numbers less than or equal to its square root. If none of the go into the number then it is a prime.
