The correct answer option is .

Step-by-step explanation:

We are given the following expression and we are to simplify it and determine whether which of the given expressions is equivalent to it, assuming and :

Breaking the terms to get:

The correct answer is third option

8x⁴yz⁴√2yz

Step-by-step explanation:

It is given that,

√128x⁸y³z⁹

To find the equivalent of √128x⁸y³z⁹

We have 128 = 2⁷

x⁸ = (x⁴)², y³ = y² * y and z⁹ = (z⁴)² * z

√128x⁸y³z⁹ = √(2⁷ * (x⁴)² * y²y * (z)⁴)²z)

  = 2³x⁴yz⁴√(2 * y * z)

 = 8x⁴yz⁴√2yz

Therefore the correct answer is third option

b. x- 48 =120
