Not mentioned a and b are integers so the last part is actually wrong

You know what you didn't write? You didn't write it with the X getting replaced with the answer to prove your claim. Also, why are you using Trigonometry to solve this?

Please put the x=5 in the expression and verify once

2^x = 20-x Y1= 2^x Y2=20-x Both are strictly increasing But y1 will faster than y2 So only one value satisfying both eqn X=1 X= 2 X= 3 X=4✓

How did we get to the conclusion that we have to multiply x by (x-3)?? You said we can see that right away but how?
@OlympiadMathExplorers Ай бұрын
If we put the value of x=3 in the expression, then the expression becomes zero. Hence (x-3) will be a factor of the expression. That's why we multiply by (x-3)

Here's how I got it with an easier way (I think) : 2^x + x = 20 With the use of 2^(a+b) - 2^b = 2^a + 2ab we get : 2^(x + 0.5) - 2^0.5 = 20 2^(x + 0.5) - 0.25 = 20 2^(x + 0.5) = 20.25 x + 0.5 = 4.5 <--- root x = 4 (I'm not learning maths in English hope you understand :D)

1) 2^x is strongly monotonic increasing over the reals 2) x is strongly monotonic increasing over the reals => 2^x + x is strongly monotonic increasing over the reals 3) 2^x + x is continous With 1) and 2) => 2^x + x is bijective => there is only one value of x for which 2^x + x = 20 4) observe 2^4 + 4 = 20 => x = 4 With 3) The solution set is {4} Qed
