" 61.यदि "(x+(1)/(x))=sqrt(13)" हो,तो "(x^(3)-(1)/(x^(3)))=" ? "

यदि x+(1)/(x)=sqrt(3) है तब x^(3)+(1)/(x^(3)) का मान होगा -

sqrt((x)/(1-x))+sqrt((1-x)/(x))=(13)/(6)

sqrt((x)/(1-x))+sqrt((1-x)/(x))=(13)/(6)

If x+(1//x)=(sqrt3+1)//2 , then what is the value of x^4+(1//x^4) ? यदि x+(1//x)=(sqrt3+1)//2 है, तो x^4+(1//x^4) का मान क्या है?

If x+1/(16x)=3 , then the value of 16x^3+ 1/(256x^3) is: यदि x+1/(16x)=3 है, तो 16x^3+ 1/(256x^3) का मान क्या होगा ?

If x+1/(16x)=1 , then the value of 64x^3+1/(64x^3) is यदि x+1/(16x)=1 , तो 64x^3+1/(64x^3) का मान है-
