Suppose we designate the number as x.

Julio's initial action is to cube this number, resulting in:

x^3

Next, he calculates the cube root of this value, leading to:

(x^3)^(1/3)

When simplified, this becomes:

x^(3/3) = x^1 = x

Since he ends with the value of 20, we conclude:

x = 20

<span>Thus, Julio both began and concluded with the number 20.</span>

a=1/100pt is the right solution. Initially, you need to multiply both sides of the equation by t, which results in ⇒ $pt=100a$ . After that, inverting the equation gives ⇒ $100a=pt$ . Alternatively, dividing both sides of the equation by one hundred (100) also leads us to $\frac{100a}{100}=\frac{pt}{100}$ . Ultimately, the final answer is a=1/100pt is the result. I hope this offers assistance! Thank you for asking your question, and enjoy your day. -Charlie
