Answer:
k=2
Step-by-step explanation:
3^k*2 * 3^-k+2 = 81
Factor out 81 to be : 3^4
Rewrite the equation:
k*2 - k+2 = 4
k^2 - 2k = 4
Simplify : k+2 = 4
<u> - 2 - 2</u>
k = 2

Answer:
x = 360
Step-by-step explanation:
Reorder the terms:
x = 72 + 0.8x
Solving
x = 72 + 0.8x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-0.8x' to each side of the equation.
x + -0.8x = 72 + 0.8x + -0.8x
Combine like terms: x + -0.8x = 0.2x
0.2x = 72 + 0.8x + -0.8x
Combine like terms: 0.8x + -0.8x = 0.0
0.2x = 72 + 0.0
0.2x = 72
Divide each side by '0.2'.
x = 360
Simplifying
x = 360
