(x2y3)1/2(x2y3)1/3=xa/3ya/2 where a is constant, is true for all positive values of c and y, what is value of a?

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
