Three to the third power equals twenty-seven. Since an exponent indicates how many times to multiply the base number to itself, this problem can also be visualized as three times three times three.
Basic positive integer exponents follow the same rule: If a number is positive and it is being raised by a positive exponent, then that number is multiplied against itself as many times as the exponent indicates. If a number is negative when it is being raised by a positive exponent, attention must be paid to whether the exponent is even or odd. An even exponent results in the solution being positive, while an odd exponent results in the solution being negative.
