D?

Let say each part = x : so 5x = 2 hence x = 2/5
\(p^1/3\) = 4x = 8/5
p = 8*8*8/125 = 512/125

You may notice that 5nos. of hash marks add up to 2. Since the hash marks are equally spaced hence gap between consecutive hash marks is \(\frac{2}{5}\).

Now, \(\sqrt[3]{p}\) is situated after 4 gaps from the reference point(0).
So, \(\sqrt[3]{p}\)=\(4*\frac{2}{5}\)
Or, \(p=(\frac{8}{5})^3\) (Taking cube both sides)
Or, p=\(\frac{512}{125}\)

Ans. (D)

There are 5 spaces between 0 and 2
So, each space represents 2/5

∛p is 4 spaces from 0.
So: ∛p = 4(2/5)
Simplify right side: ∛p = 8/5
Cube both sides to get : (∛p)³ = (8/5)³
Simplify: p = (8/5)³ = 512/125

Answer: D

Cheers,
Brent
