Question

prove that 102×(30-20)=(102×30)-(102×20)​

Answer 1

Answer:

(102)×(30-20)=(102×30)-(102×20)

102×10=(3060)-(2040)

1020=1020

L.H.S=R.HS

Hence,proved that 102×(30-20)=(102×30)-(102×20)

Answer 2

Proving 102x(30-20) = (102x30) - (102x20).

Given,

102x(30-20) = (102x30) - (102x20)

To Find,

102x(30-20) = (102x30) - (102x20)

Solution,

Firstly, taking Left Hand Side(L.H.S)

⇒ 102x(30-20) = 102x10

                        = 1020

Now, taking Right Hand Side(R.H.S)

⇒ (102x30) - (102x20) = 3060 - 2040

                                    = 1020

We can see that L.H.S = R.H.S

Hence proved, 102x(30-20) = (102x30) - (102x20).
