this can be multiplied as x should be positive , then equation will be

x^7 > y^4

by combining both the statements we can say x>y .

Sorry i thought in a wrong way .. it can't be proved like that .

it is implied when we combine both the statements that x>0

take 3 case

1=> x=1/16 y=1/7;

2=>x=2 y=7;

3=> x=9 y=7;

by this we can say that data is not sufficient .

P.s : If i am wrong kindly correct me ..

The question can not be answered even by using both the statements together?

I am confused about my answer can any one confirm me what the correct answer ??

thank you in advance . :)

Question :

choice 1 : if the question can be solved by using one statmnt and can't be solved by another statement .

choice 2: if the question can be solved by...

1

my bad...actually i did not solve the root equation..i assumed a value will be obtained...

1

that if we apply that square root formula,we will get two roots...

n so for data sufficiency we need distinct ans...

which formula will u use to calculate d 3rd side ?

cannot be determined is the answer

both statements required

what is the 3rd side of a triangle?

1) 2 sides are 10m & 20m

2) area is 80sq.m

Data sufficiency

1) 2 sides are 10m & 20m

2) area is 80sq.m

Data sufficiency

cannot be determined

(n+k)^1/2 > 2( n)^1/2

squaring on both sides

n+k>4n

=> K>3n

squaring on both sides

n+k>4n

=> K>3n

statement 1 is sufficient to answer the question?

Mark (a) if the question can be answered by using either statement alone.

Mark (b) if the question can be answered by using one of the statements alone, but cannot be answere...

Q) Is x > y?

(1) x > y

(2) x^3 > y

(1) x > y

(2) x^3 > y
