The numbers up to 100 that are perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100. A perfect square is a number that is the result of a smaller number multiplied by itself.Know More
Square numbers follow the form n^2, where "n" is a whole number. This is the same as n x n. With a given number that is a perfect square, you can find the next number that is a perfect square. For example, if you are given the number 16, which has a root of four, you can add four and five to get nine and add this to 16. This equals 25, which is a perfect square of root five. One important point is that a perfect square can not be negative. Taking the root of a negative number would lead to an imaginary number.
The history of square roots dates back to the ancient Egyptians. While the exact methodology of how these individuals arrived at finding these numbers isn't known, one conjecture is that they used a right angle with two equal arms. The two arms were multiplied and a perfect square was produced. A second right angle would produce a square.Learn More
Indices are a mathematical concept for expressing very large numbers. They are also known as powers or exponents. In the mathematical process of exponentiation, a base number is written alongside a superscript number, which is the index or exponent.Full Answer >
The Roman numeral "XLV" translates into the number "45." The Roman numeral system uses letters to represent numerals in a number. Letters used for numbers up through 100 are 'I" for one, "V" for five, "X" for 10, "L" for 50 and "C" for 100.Full Answer >
An endless number of digits are in pi. It is an irrational number, which means it cannot be expressed as the ratio of any two integers. Furthermore, it was proved in 1882 that pi is not the root of an algebraic equation that has rational factors.Full Answer >
A linear pattern exists if the points that make it up form a straight line. In mathematics, a linear pattern has the same difference between terms. The patterns replicate on either side of a straight line.Full Answer >
