Most complicated and written out explanation for 1 plus 1 can get 20 points and brainliest.

looking at the equation one plus one we see there can be many answers for example we can take one plus ine and change it to a number of different questions including but not limited to 1+1 1-1 1/1 1x1 1^1 etc looking at other results we can then determine tat 1+1=2 all though alternative answers could be present

Step-by-step explanation:

1) f(x)=-3×4⁽¹⁻ˣ⁾ <--- this can be broken into two segments as seen below 
f(x)=-3x4¹(4⁻ˣ) 
f(x)=-12(4⁻ˣ) 

2) f(x)=log₅(x-2)+log₅(3x+7) <--- since the logs are same, you can add them 
f(x)=log₅((x-2)(3x+7))
f(x)=log₅(3x²+7x-6x-14) 
f(x)=log₅(3x²+x-14) 

I graphed this equation to find the zeros as -2.4 or 2.07. 

3) c⁽⁴ⁿ⁺¹⁾=7a-b 
logc(7a-b)=4n+1 

Hope I helped :)
