please answer 4 th one

Answer 1

$\bold{x^{\frac{1}{12}}=(49)^{\frac{1}{24}}} \\ \\ \bold{x^{\frac{1}{12}}=(7^2)^{\frac{1}{24}}} \\ \\ \bold{x^{\frac{1}{12}}=7^{2 \times \frac{1}{24}}} \\ \\ \bold{x^{\frac{1}{12}}=7^{\frac{2}{24}}} \\ \\ \bold{x^{\frac{1}{12}}=7^{\frac{1}{12}}} \\ \\ \bold{(x^{\frac{1}{12}})^{12} =(7^{\frac{1}{12}})^{12}} \\ \\ \bold{x=7} \\ \\ \\ \\ \bold{\therefore\ x=7}$
