Answer is 0</h3>
===========================================================
Explanation:
Logarithms are used to solve exponential equations. Specifically if you have a variable in the exponent, then you use a log to isolate the variable.
If we set the given log expression to x, then we can rewrite it into 8^x = 1. The only value of x that works is x = 0.
------------
Or put another way,
8^x = 1
8^x = 8^0 ... replace the 1 with 8^0
x = 0 ... the bases are equal (to 8) so the exponents must be equal
------------
You can use the change of base formula to directly calculate this log

Answer:
x=9, y=-4. (9, -4).
Step-by-step explanation:
2x+5y=-2
4x+7y=8
--------------
-2(2x+5y)=-2(-2)
4x+7y=8
---------------------
-4x-10y=4
4x+7y=8
--------------
-3y=12
y=12/-3
y=-4
2x+5(-4)=-2
2x-20=-2
2x=-2+20
2x=18
x=18/2
x=9
