10
10 to the power of 9 (109) is one billion (US) or giga- so 109 Hz is 1 GHz.
1/9
-9
Any number (except 0) raised to the power of 0 is equal to 1. Therefore, 9 to the zero power is 1, and 11 to the zero power is also 1. So, 9 to the zero power plus 11 to the zero power is equal to 1 + 1 = 2.
It remains as -1
1 everything to the power of 0 = 1
The answer is 9. 23 = 8 90 = 1 8 + 1 = 9 I think you meant 8. 8*1 = 8
it is 1

9-8 = 1/98 = 1/43046721
3-2 + 1 = 1/ 32 + 1 = 1/9 + 1 = 1/9 + 1(9/9) = 1/9 + 9/9 = (1 + 9)/9 = 10/9 = 1 1/9 or3-2+1 = 3-1 = 1/3
