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
