❏ Basic method to solve this type of equality is to make the variable term in exponent of 1.

 \; \; \;

❏ By using some mathematical operations we need to make variable term with the degree of 1.

 \; \; \;

❏ Let's see how can we solve this question .-.

\underline{\boxed{\bold{\bigstar \; Answer \; \bigstar}}}

Let's Start !

  \; \; \;  

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  \; \; \;  

Here we are given ;

 \; \; \;

\bold { \red{:\implies \sqrt[3]{4x-7}  = 5 }}

 \; \; \;

Now let's cube both side !

Mathematically ,

 \; \; \;

\bold { \orange{:\implies (\sqrt[3]{4x-7})^3  = 5^3 }}

\bold { \blue {:\implies 4x-7  = 5^3 }}

\bold { \orange{:\implies 4x-7  = 125 }}

\bold { \blue{:\implies 4x  = 125 + 7 }}

\bold { \orange{:\implies 4x  = 132 }}

\bold { \blue{:\implies x  = \dfrac{132}{4} = 33  }}

 \; \; \;

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  \; \; \;  

\boxed{\boxed{\bold{\therefore Value\;of\;x = 33}}}

  \; \; \; ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

 \; \; \;
