Since this is a cube, we can use the volume formula for a cube.

s is the lenght of one of the edges of the cube.
The edge of the cube has a length of 4.2 in. Let's plug it into the formula.


That's your answer. I hope this helps! :)
Which is the following product? Assume x ≥ 0
![\sqrt[3]{x^{2}} \times\sqrt[4]{x^{3}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B2%7D%7D%20%5Ctimes%5Csqrt%5B4%5D%7Bx%5E%7B3%7D%7D)
A. 
B. ![\sqrt[12]{x^{5}}](https://tex.z-dn.net/?f=%5Csqrt%5B12%5D%7Bx%5E%7B5%7D%7D)
C. ![x\sqrt[12]{x^{5}}](https://tex.z-dn.net/?f=x%5Csqrt%5B12%5D%7Bx%5E%7B5%7D%7D)
D. 
Answer:
C. ![x\sqrt[12]{x^{5}}](https://tex.z-dn.net/?f=x%5Csqrt%5B12%5D%7Bx%5E%7B5%7D%7D)
Step-by-step explanation:
NOTE : ![\sqrt[n]{x^{m}}=x^{\frac{m}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D%3Dx%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D)

![\sqrt[3]{x^{2}} \times\sqrt[4]{x^{3}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B2%7D%7D%20%5Ctimes%5Csqrt%5B4%5D%7Bx%5E%7B3%7D%7D)









![=x\sqrt[12]{x^{5}}](https://tex.z-dn.net/?f=%3Dx%5Csqrt%5B12%5D%7Bx%5E%7B5%7D%7D)
