If (x - b)^(1/3) = c^6, then x = ?

Question

If  \sqrt {x - b} = c^6 , then  x =  ?

A. c^2 + b
B. c^6 + b
C. c^9 + b
D. c^12 + b
E. c^18 + b

PrashantLakhotia · Answer

On Cubing both the equations, we get 
x-b = (c^6)^3 which can also be written as
x-b = (c^6)(c^6)(c^6) and hence we get x = (c^(6+6+6)) + b.
Therefore, E.

X= C^ 18+b. IMO, E is the Answer

joohwangie · Answer

(x-b)^1/3=c^6

^3=(c^6)^3

x-b=c^18

E
x=c^18+b

Abhishek009 · Answer

\sqrt {x - b} = c^6

Or,  x - b = c^{18}

Or,  x = c^{18} + b , Answer must be (E)

siddharthkapoor · Answer

On cubing both the sides of the equation we get,
x-b=  c^{18} 
=> x= c^{18}  +b

Therefore, the answer is option E.

Abhishek009 · Answer

\sqrt {x - b} = c^6

x - b = c^{18}

Or,  b = c^{18} - b , Answer must be (E)
