Answer 2

Answer of this question is $\frac{67}{2}$.

Step-by-step explanation:

We are given,

$(1^3 +2^{3} + 3^{3} )-\frac{5}{2}$

To solve this question let us take two constants a and b , a for $(1^{3}+2^{3}+3^{3} )$ and b for $\frac{5}{2}$ now we have to find the $a-b$.

• First we solve the cube terms separately  such as,

      $1^{3} = 1*1*1=1$

      $2^{3} = 2*2*2=8$

      $3^{3}=3*3*3=27$

• Calculation for a that is addition of cubic terms,

      $a=(1^{3}+2^{3}+3^{3} )$

      $a=(1+8+27)$

      $a= 36$

• Calculation for (a-b),

     We have $a= 36$ and b= $\frac{5}{2}$

     Now $(a-b)=36-\frac{5}{2}$

• Taking L.C.M as 2 and we get,

        $a-b=\frac{72-5}{2}$

                  $=\frac{67}{2}$

We get our answer as $\frac{67}{2}$.
