33/8 < exact form
4.125 < decimal form
4 1/8 < mixed number form
Answer:
B
Step-by-step explanation:
Comparing like terms on both sides
→ x²
Note that x² = ![\sqrt[3]{x^{6} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B6%7D%20%7D)
→ 
Note that
= ![\sqrt[3]{y^{12} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7By%5E%7B12%7D%20%7D)
Also
54 → 3
Note that 54 = 3³ × 2
and
=
= 3![\sqrt[3]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2%7D)
Hence
= 3x²
![\sqrt[3]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2%7D)
Hence n = 3 → B
The verbal expression is one eighth times y
