Math

Step-by-step explanation:

√2 is incorrect because when we evaluate the square root, we will get a never-ending decimal: 1.4142135623731...

3.44444444... is incorrect because it is a never-ending decimal (the bar above 4 signifies this).

√10 is incorrect because when we evaluate the square root, we will get a never-ending decimal: 3.1622776601684...

√16 is correct because when we evaluate the square root, we get a ending decimal/a whole integer: 4

Therefore √16 is the correct answer.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

x= cost per bracelet
