Which of the following is true?
$$\eqalign{
& {\text{I}}.\root 3 \of {11} > \sqrt 7 > \root 4 \of {45} \cr
& {\text{II}}.\sqrt 7 > \root 3 \of {11} > \root 4 \of {45} \cr
& {\text{III}}.\sqrt 7 > \root 4 \of {45} > \root 3 \of {11} \cr
& {\text{IV}}.\root 4 \of {45} > \sqrt 7 > \root 3 \of {11} \cr} $$
Answer & Solution
Correct Answer:
Option
C
$$\eqalign{
& \root 3 \of {11} ,\,\sqrt 7 ,\,\root 4 \of {45} \cr
& {11^{\frac{1}{3}}},\,{7^{\frac{1}{2}}},\,{45^{\frac{1}{4}}} \cr
& {\text{Take LCM of 3, 2, 4 is 12}} \cr
& {11^4},\,{7^6},\,{45^3} \cr
& {\text{14641,}}\,{\text{117649,}}\,{\text{91125}} \cr
& 117649 > 91125 > 14641 \cr
& {\text{Option C is true}} \cr
& \sqrt 7 > \root 4 \of {45} > \root 3 \of {11} \cr} $$
