Answer:
x=3.6
Step-by-step explanation:
You subtract 0.68 from 5 and you get 1.2=4.32
Then you put 1.2 under 1.2 and 4.32 to get x on its own on that side you equation now looks like this x=3.6 So that is your answer
The last one x^4.
A: If you bring 2^-5 to the numerator which is what the - expects you to do, then you get x^5 which is 32
B: No problem here. 32 = 32
C: 2^1 * 2^4 = 2^(1 + 4) = 2^5.
C: 2^5 is 32
D: 2^4 = 16.
Answer: D does not agree with the others.
It’s an irrational number (can’t be expressed as a fraction with two integers).
