What is the smallest no.by which 539 should be multiplied, so that the product is a perfect square?

Answer»

Let's factorize 539 by LCM.


11 | 539

7 | 49

7 | 7

| 1


539 = 11 X


11 x 7² multiplied by 11 gives 11² x 7² = (11 x 7)² = 77².


∴ 11 is the smallest number by which 539 is multiplied to get a perfect square as the product.


539 x 11 = 5929 = 77²

Let the MISSING no. Be as X
X-15=80/100*X
100(X-15)=80X
100X-1500=80X
100X-80X=1500
20X=1500
X=1500/20
X=75

ATQ
40% of that no. X will be as

40/100*25
1000/100
10
Therefore 10 is the answer.

if one zero of the polynomial 2xsquare – 5x – (2k+1 ) is twice the other, then find both the zeroes and the value of k

Answer»

hy\\friend


LET, p(X)=2x²-5x-(2k+1)--------(1)

Also let, α be one ROOT of (1).

Then the other root will be 2α.


α+2α=-(-5)/2


⇒ 3α=5/2


⇒ α=5/6


Again, α×2α=-(2k+1)/2


⇒ 2α²=-(2k+1)/2


⇒ -(2k+1)/2=2×(5/6)²


⇒ -(2k+1)=4×25/36


⇒ -2k-1=25/9


⇒ -2k=25/9+1


⇒ -2k=34/9


⇒  k=-34/9×1/2


⇒ k=-17/9 Ans.

Answer»

Some basic properties are....

●The sum of the ANGLES in a TRIANGLE is 180°. This is called the angle-sum property.

●The sum of the lengths of any two sides of a triangle is greater than the LENGTH of the third side. Similarly, the difference between the lengths of any two sides of a triangle is less than the length of the third side.
