Answer:
36
Step-by-step explanation:
Let the unknown be x


Both the base number are 3, so we equate the exponent:




Answer: 1/6
Substitute in the values and solve.
1) B
For A:
3 = 4(1)
<u>This is NOT true.</u>
For B:
-4 = 4(-1)
<u>This IS true.</u>
For C:
-1 = 4(-4)
<u>This is NOT true.</u>
For D:
-4 = 4(1)
<u>This is NOT true.</u>
2) None. Possible solutions: (0,2) (1,-5)
For A:
2 = -7(1) + 2
2 = -7 + 2
<u>This is NOT true.</u>
For B:
-52 = -7(8) + 2
-52 = -56 + 2
<u>This is NOT true.</u>
For C:
-35 = -7(5) + 2
-35 = -35 + 2
<u>This is NOT true.</u>
For D:
-7 = -7(1) + 2
-7 = -7 + 2
<u>This is NOT true.</u>
