Final answer:
The expressions that are equal to 'five to the third power' are 5^3, 5 * 5 * 5, and 125, as they all represent the number 5 multiplied by itself a total of 3 times.
Step-by-step explanation:
The expressions that are equal to "five to the third power" or 53 are 5 * 5 * 5 and 125. The expression 53 represents the number 5 multiplied by itself three times, which equals 125. It is important to understand that the base number is 5, and the exponent is 3, which means you need to multiply 5 by itself two more times after the first 5. So, the correct way to express five to the third power is either by using the exponent notation 53, writing it out as a series of multiplications 5 * 5 * 5, or just stating the result of this calculation, which is 125.
In comparison, 3 * 3 * 3 * 3 * 3 does not equal 53 because it is five 3s multiplied together, not threes. The number 15 is simply the sum of 5 three times, and the number 243 is actually 35 (three to the fifth power). Finally, 35 is just the numbers 3 and 5 written next to each other without any operation signifying exponentiation.
