All you need to do is divide both sides by -7. Once you divide -56 by -7, you get 8. So k=8.
Answer:
![x \cdot y=1](https://tex.z-dn.net/?f=x%20%5Ccdot%20y%3D1)
Step-by-step explanation:
![(7^x)^y = 7](https://tex.z-dn.net/?f=%287%5Ex%29%5Ey%20%3D%207)
Apply exponent rule
:
![\implies7^{xy}=7^1](https://tex.z-dn.net/?f=%5Cimplies7%5E%7Bxy%7D%3D7%5E1)
![\implies x \cdot y=1](https://tex.z-dn.net/?f=%5Cimplies%20x%20%5Ccdot%20y%3D1)
Possible values for x and y: ![x=\dfrac12 \ \ \ \ \ y=2](https://tex.z-dn.net/?f=x%3D%5Cdfrac12%20%5C%20%5C%20%5C%20%5C%20%5C%20%20y%3D2)

Answer:
-13 -i
Step-by-step explanation:
The first step is to find the sum
5-9i and -4+7i
Add the real parts and then the imaginary parts
5+-4 = 1
-9i + 7i = -2i
5-9i + -4+7i = 1 -2i
Now we subtract 14 -3i
1 -2i - (14 -3i)
Subtract the real parts and then the imaginary parts
1-14 = -13
-2i - -3i = -2i+3i = i
1 -2i - (14 -3i) = -13 -i
It is 2.18 First you have add 3.57 +2.97 then with your answer you have to divide it, which would give you 2.18
