1.)1

2.)1/5

3)(square root 5)^7

4.)3 suare root 25

5.)square root 125

6.)1/ square roor 5

1. r = 0 (anything to the 0th power is 1)

2. y = 5^x

1/5 = 5^x

x = -1

3. sqrt(5)^7 = 5^x

x = 7/2

4. cube root (25) = 5^x --->

25 ^1/3 = 5^x

25= 5^2

x = 2/3

5. sqrt(125) = 5^x

125 = 5^3

125^1/2 = 5^x

5^3/2 = 5^x

x = 3/2

6. 1/sqrt(5) = 5^x

5^-1/2 = 5^x

x = -1/2
