Answer:
see the explanation
Step-by-step explanation:
we know that
To determine the rate per pretzel or unit rate, divide the total paid by the number of pretzel
so
![\frac{126}{42}=\$3\ per\ pretzel](https://tex.z-dn.net/?f=%5Cfrac%7B126%7D%7B42%7D%3D%5C%243%5C%20per%5C%20pretzel)
<em>Jaimie's error</em>
He subtracted 42 from $126 when he should have divided $126 by 42
So here is how we are going to solve this:
The power of the given expression is 3 and the root is 5. So in writing a fractional exponent, we just have to make 3 as the numerator. So multiply both sides by 3/5 to take the root sign off and the final answer would be x^3/5. 3/5 is the power. Hope this answer helps.
2(4)2 - 10 / 2 = 8(2) - 10 / 2 = 16 - 5 = 11 (FINAL ANSWER)
