Let us say that the number is x.
So the first step that Julio do is to cube the number so
that:
x^3
Then the next he did was take cube root of the number, so
that:
(x^3)^(1/3)
Solving this would result in:
x^(3/3) = x^1 = x
Since he ends up with 20, therefore:
x = 20
<span>Julio started and ended with the same number which is 20.</span>
Apply quotient rule and chain rule and power rule.
Differentiate both sides with respect to x
You'll get
18 26 30 but i dont know the rest sorry
Answer:
t^2 -4t + 4
Step-by-step explanation:
(2t-4)(2t-4) Use the FOIL Method (first, outside, inside, last)
2t*2t =4t^2 First
2t*-4 = -8t Outside
-4*2t = -8t Inside
-4*-4 = 16 Last
4t^2 -8t -8t + 16 (simplify/add like terms)
(4t^2 -16t + 16)/4 (you can further simplify by dividing each value by 4)
t^2 -4t + 4
