The expression 2 to the power of 1 is calculated as follows:
When we raise a number to a power, we are essentially multiplying that number by itself a certain number of times. In this case, the expression means multiplying 2 by itself just once (because the exponent is 1).
Therefore, 21 = 2.
This means that 2 to the power of 1 equals 2. The power of an exponent indicates how many times to use the number in multiplication. Since we only have 1 here, the answer is simply the base number itself.
