I chose 4 1 , because:
□ 4 1 = 2 1
so 2 1 > 4 1
root of 1/4 is 1/2, that is 0.5.. square of 1/4 is 1/16, that is 0.0625.. therefore 0.5 is greater than 0.0625
The numerator should be minimum as possible, it can't be zero since square root of 0 is equal to square of zero . Thus it should be one , only one option contains it .
Check for the given options as per given condition
If a < b then ( b a ) 2 = b 2 a 2 which is smaller because b − a < b 2 − a 2 ⟹ b − a < ( b − a ) ( b + a )
It simply telling that x<1... So just option checking..😉
Let x=1/4, and 1/4=0.25 and its(1/4) square root is 0.5 while the square of 1/4 =0.0625. Thus, x = 1/4 in that the square root of 1/4 which is 0.5 is > then (1/4)^2 which is 0.0625.
WHAT!!!!! 😨😨
x > x 2 = > x > x 4
Thus for any value of x for which − 1 < x < 1 excluding 0 , the multiple of itself will yield a value less than itself (i.e 0.5 x 0.5 = 0.25 < 0.5)
So hence, x = 4 1
because the square of 0<x<1 is smaller always than their respective square roots :)
if any no is less then one the its square is always less then square root of it self
If x = 1/4 then 1/4 ^ 1/2 is equal to 1/2 which is equal to the square root of x
x^1/2 > x ; 1/2 >1/4
let x=1/4 then square root of 1/4 is 1/2 so 1/2=.5 is greater than 1/4=.25. so ans is 1/4. best wishes next
sqrt(1/4) = 1/2, half is greater than 1/4
sqrt(1/4)=0.5 >(1/4) ((0.5)^2) basically given any real number n, such that 0<n<1 will satisfy the given condition for further explanation try graphing both y=sqrt(x) and y=x on the same axis
which is greater value cos6 or cos60
1/4 = 0,25. √0,25 = 0,5. This satisfies the proposition.
Write a comment or ask a question...how a square root can be greater than its square even square root can be imaginaryy too ? pls answer
x > x will happen when 0 < x < 1
Then, the answer is 4 1 .

We know that square of any value b/w 0<x<1, then its resultant value less than its original value. apply square both side, here only one value 1/4
