The product of negative three squared is nine. To square a number means to multiply that number by itself, and multiplying two negatives together yields a positive number, as About.com explains. Negative three times negative three, therefore, is nine.
Know MoreA negative number is never a perfect square. The smallest perfect square possible is zero because zero times zero is zero. The square root of a number is potentially either positive or negative. For example, the square root of nine is three or negative three. Squared odd numbers always have an odd result, and squared even numbers always yield an even result. In this case, negative three is odd, and its square is nine, which is also odd.
Learn more about ExponentsThe factors of 100 are 2, 2, 5 and 5. To find the prime factorization of a number, the number is divided by prime numbers that go evenly into the original value until only one prime number is left. For example, 100 divided by 2 is 50, and then 50 divided by 2 is 25, and then 25 divided by 5 is 5, giving the prime factorization of 2 x 2 x 5 x 5.
Full Answer >The prime factorization of 49 is equal to 7*7. The prime factorization of a number is a way of representing a number as the result of two or more prime factors.
Full Answer >To find the y-intercept of a line, substitute the values of x and y coordinates into an equation representing the line. Set x to 0, then solve for y. If the equation is already in the slope-intercept form of y = mx + b, the value of b is the y-intercept.
Full Answer >An exponent tells the problem solver how many times to multiply a number by itself; therefore, a zero exponent tells the problem solver to multiply the number zero times by itself. Basically, any number with a zero exponent is equal to one, unless the base number is zero.
