Answer:
1^a =1
0^a = 0 a>=0
Step-by-step explanation:
The value of 1 ^a = 1
One to any power is 1
1 multiplied by 1 any number of times is still 1
a>0
1^a = 1*1*1*1...... a times It will always be 1
a<0
1 divided by 1 any number of times is 1
1/ 1^a = 1 /( 1*1*1*1...... ) a times is still 1
The value of 0^a a>=0 is 0
0*0*0 ...... a times equals 0
Since a >=0 we are always multiplying by 0
