7 to the power of 3, written mathematically as 73, is equal to 343.
To find this value, you multiply 7 by itself three times:
7 × 7 × 7 = 49 (which is 7 squared) and then you multiply that result by 7 again:
49 × 7 = 343.
Therefore, 73 = 343. This operation is part of exponentiation, where the number 7 is known as the base and the number 3 is called the exponent, indicating how many times the base is multiplied by itself.
