√3x² - 2√2x - 2√3 = 0 √3x² - 3√2x + √2x - 2√3 = 0 √3x(x -√6 ) + √2(x -√6)=0 (√3x+√2) (x- √6)=0 (√3x+√2) =0 || (x- √6)=0 x= -√2/√3 || x= √6

First draw the diagram. Then take height of tower as x. Also tan 30=10/y 1/√3=10/y y=10√3 Use it to find height of tower. Tan 60=10+x/10√3 √3=10+x/10√3 30=10+x x=20 Therefore height of tower is 20m

Let the point be (x,0) because it lies on x axis so y is 0 Find OA first with this formula  √(x¹-x²)^2+(y¹-y²)^2 Then find OB you will get something with values of x since they are equal equate both expression then you will get the value of x either directly or an equation after solving you will get x .

Let assume that √7 is a rational number. So, √7=a/b (a & b are Co-prime number & b is not equal to 0) Squaring both side (√7)^2 = (a/b)^2 7 = a/b^2 7b^2 = a^2 Therefore, 7b^2 divides a^2 & a. ---------(1) Again, Let the a^2 = m^2 7m^2 = b^2 7a^2 = b^2 Therefore, 7a^2 divides b^2 & b. ---------(2) By equations (1) & (2), We get that, Our assumption is wrong. So, √7 is an Irritaional number.

Let us assume that 7​ is rational. Then, there exist co-prime positive integers a and b such that 7​=ba​ ⟹a=b7​ Squaring on both sides, we get a2=7b2 Therefore, a2 is divisible by 7 and hence, ais also divisible by7 so, we can write a=7p, for some integer p. Substituting for a, we get 49p2=7b2⟹b2=7p2. This means, b2 is also divisible by 7 and so, b is also divisible by 7. Therefore, a and b have at least one common factor, i.e., 7. But, this contradicts the fact that a and bare co-prime. Thus, our supposition is wrong. Hence, 7​ is irrational.

first assume it as a rational number And then solve Answer = Root 5 +root 3 =p/q where q is not equal to 0 Root 5 + root 3 ×q =p Root 3 = p/5q Since root 3 is an irrational number and p/q is isn't clear So root 5+ root 3 is an irrational number.

Assume that you have 4 friends with you. You don't have any car, but you want to distribute the cars you have, among them equally. Will it be possible? No, because you cannot share something that does not exist in the first place.
