In this case, you can see that 102 = 100. This is because you’ve found the exponent, 2, subtracted 1 from it to get 1, and then added just 1 0 after “10” to get 100, your answer.
For example: 103 = 1000 because 10 x 10 x 10 = 1000. 104 = 10 x 10 x 10 x 10 or 10,000. 105 = 10 x 10 x 10 x 10 x 10 = 100,000. 106 = 10 x 10 x 10 x 10 x 10 x 10 = 1,000,000 107 = 10 x 10 x 10 x 10 x 10 x 10 x 10 = 10,000,000
Therefore, 100 = 1, 50 = 1, 210 = 1, and so on. You can also think of it this way: 10 to the power of 0 is 1 because 0 is the amount of zeros that go after 1 and if zero zeros are after 1, that makes the answer 1.
