If `1/8 :1/12 = 3:x` then x = ?

If 3x-1=8 ,then x=

If X -1/x=8, then x^3 -1//x^3=?

If (8/3)^(3-x) = (3/8 )^(2x-1) , then x =

If x= 11, then the value of x^5 -12x^4 +12x^3 -12x^2+12x-1 is - यदि x= 11 हो तो x^5 -12x^4 +12x^3 -12x^2+12x-1 का मान क्या होगा?

f(x) = {:((sqrt(x+3)-2)/(x^(3)-1)", if " x!=1),(=1/12", if " x=1):}} at x = 1 , si
