The cube root of what integer power of 2 is closest to 50? Choose the correct choice:	A) 16	B) 17	C) 18	D) 19	E) 20
Integer powers of 2 = 2 , 2^2, 2^3, 2^4, 2^5, 2^6, 2^7 etc.   Let, Cube root of x is closest to 50   i.e. x is closest to cube of 50 = 50*50*50=

<output>125_000</output>
125000   But x must be equivalent to an Integer power of 2   2^10= 1024   2^7 = 128   i.e. 2^17 = 128*1024 = 128000 (approx.)   i.e. 2^18 = 256*1024 = 256000 (approx.)   i.e. 2^16 = 64*1024 = 64000 (approx.)   i.e. 2^17 which is closest to 125000   i.e. Integer power of 2 must be 7   Answer: option 17
