**Use suitable identities to find the following products:**

**(i)** **(ii)** ** (iii)**

**(iv)** ** (v)**

**Solution (i)**

Here, we can use an identity: ** (1)**

In this problem, we have a=4 and b=10.

So, putting values in **(1)**, we get

**Solution (ii)**

Here, we can use an identity: ** (1)**

In this problem, we have and

So, putting values in **(1)**, we get

**Solution (iii)**

Here, we can use an identity: ** (1)**

In this problem, we have and .

So, putting values in **(1)**, we get

**Solution (iv)**

Here, we can use an identity: ** (1)**

We have and

Putting values in** (1)**, we get

**Solution (v)**

Here, we can use an identity: ** (1)**

We have and

Putting values in** (1)**, we get
