Question

Verify 18×(7×(-3)=18×7+18×(-3)

Is LHS= RHS ?​

Answer 1

Answer :

To verify an equation, we need to see if the LHS = RHS.

Equation
`\downarrow`

`18*(7*(-3))=18*7+18*(-3)`

Let's solve the left hand side (LHS) first.

`18*(7*(-3))\\= 18 * (-21)\\=\underline{ -378}`

Now, let's solve the right hand side (RHS).

`18*7+18*(-3)\\= 126 - 54\\=\underline {72}`

But,

`\boxed{-378 \\eq 72}`

We can see that the LHS doesn't match or isn't equal to the RHS.

Hence, we can say that LHS
`\\eq` RHS & the equation is NOT true.

`\rule{150pt}{2pt}`

Answer 2

`18*(7*(-3))=18*7+18*(-3)\\18*-21=126 - 54\\-378 \\eq 72`

LHS
`\\eq` RHS
