Question

pls solve this problem...?

Answer 1

Information given :

$a = 2^3\times 3$

$b= 2\times 3\times\times5$

$c=3^n\times5$

L.C.M ( a, b , c ) = $2^3\times 3^2\times5$

LCM of $2^3\times 3 , 2\times3\times5 , 3^n\times5$

             $\implies 2^3\times3^n\times5$

Given :

            $2^3\times3^n\times\times5=2^3\times3^2\times5$

Comparing the powers :

$n=2$

The value of n is 2
