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 exponential parent function is the most basic form of an exponential function. From the general form of an exponential function y = ab^x, an exponential parent function has a value for a equal to one. Therefore, the exponential parent function is written simply as y = b^x.
Full Answer >The square root of 17 is approximately 4.12. Since 17 is a prime number, it cannot be rewritten in simplified radical form. The square root of 17 can be found by using the radical sign function on both scientific and graphing calculators.
Full Answer >An expression or variable with negative exponents represents the reciprocal of that expression or variable with the same positive exponent. Write the expression or variable as its reciprocal with the equivalent positive exponent; in other words, write the expression as 1 divided by the expression with its equivalent positive exponent.
Full Answer >The principal square root of 160 is 12.65 to two decimal places. The other square root of 160 is minus 12.65 to two decimal places. All real numbers have two square roots, one of which is the negative of the other.
