"hello everyone my name is shusher and
welcome back to another homework session
of plato
let's take a look at today's question
write t for true
and f for false for each of the
statements given below
and this statement is the sum
of two perfect squares is a perfect
square
all right so what you're going to do
we're going to take an example of two
perfect squares and then we'll add them
up and see
so let's take example let's take the
square of
2 square 2 square is 4
and 3 square 3 square is 9
let's add them up let's add 2 square
plus 3 square
so 4 plus 9 correct this is 13
it is not a perfect square
right not a perfect square
let's take example of 4 square and 5
square 4 square is 16
5 square is not 5 square let's take
example of 4 square and 3 square
all right so 3 square is already 9 so
let's add up 3 square and 4 squared
this is 3 square is 9 4 square is 16
this is 25
25 is a perfect square root because it
is the square of 5 so
is a perfect square so what do i see
i see that sometimes i am getting a
perfect square and sometimes
i will not get a perfect square right so
is the given statement correct they are
saying the sum of two
perfect square is a perfect square so
they are basically implying that
whenever you add two perfect squares you
will get a perfect square
which is not the case as a as i've seen
in the first example that
we're getting not a perfect square so it
can be any any
any number right it can either be a
perfect square and it
may not be a perfect square so it is not
necessary that the sum of the perfect
square will be
therefore the given statement is false
all right it is not necessary that the
sum of two perfect square is always a
perfect square
all right it can be any number so that's
it for this question if you have any
doubt you can drop
a comment and don't forget to like and
subscribe to this channel for regular
updates thank you i'll see you next time
