If 3√x+(3√3375) ^3 =17 , then find the cube root of x-1026 is equal to​

Answer»

SOLUTION :-

GIVEN :-

\sf{ \sqrt[3]{x +  { \bigg( \sqrt[3]{3375}  \bigg)}^{3} } = 17 }

TO DETERMINE :-

\sf{  \sqrt[3]{x - 1026} }

EVALUATION :-

Here it is given that

\sf{ \sqrt[3]{x +  { \bigg( \sqrt[3]{3375}  \bigg)}^{3} } = 17 }

Taking cube in both sides we get

\sf{ {x +  { \bigg( \sqrt[3]{3375}  \bigg)}^{3} } =  {(17)}^{3}  }

\implies \sf{ {x +  { \big( 15 \big)}^{3} } =  4913 }

\implies \sf{ x +  3375 =  4913 }

\implies \sf{ x  =  4913 - 3375 }

\implies \sf{x = 1538}

\therefore \:  \:  \:  \sf{  \sqrt[3]{x - 1026} }

=  \sf{  \sqrt[3]{1538 - 1026} }

=  \sf{  \sqrt[3]{512} }

= \sf{  \sqrt[3]{(8 \times 8 \times 8)} }

=  \sf{8}
