Correct opt. a)
Solve with complete solution​

Answer 1

Answer:

correct answer is option a check it

Answer 2

Answer:

Step-by-step explanation:

Let first be a and common ratio be r

So a = 1

ar⁴=2

r⁴=2

r=2^(1/4)

x=2^(1/4)

y=2^(2/4) =2^(1/2)

z=2^(3/4)

xyz = 2^(1/4)*2^(1/2)*2^(3/4)

=2^(3/2)

=2√2
