(a) Yes, he is correct. The value of x is 136.
(b) From the factor tree,
z = 2*17 = 34 .......[i]
y = 2*z = 2*34 ......[ using (i) ]
:. y = 68 ...........[ii]
Now,
x = 2*y = 2*68 .....[ using (ii) ]
Therefore, x = 136.
Hence proved.

Answer:
Yes, his answer is correct.
Step-by-step explanation:
The prime factorization of x is 2^3*17 as per the figure. And when they are all multiplied together, the product is 136.
Therefore, it is obvious that the value of x is 136.
