Hi, Assuming the question as, y = 21logx8= 2log8x    As logab= 1logba=2log23x= 213log2x    As logamb= 1m1logba=2log2x13= x13    As we know that alogab= bso x = y3

if y=21/log x8 , then x equal to the options are a)y b)y2 c)y3 d)none of these

if y=2^1/log _{x^{8 ,}} then x equal to the options are a)y b)y² c)y³ d)none of these
