Answer:
You just take the square root of both sides. Square root of
x
2
would give you an x.
√
256
would give you 16.
Step-by-step explanation:
One way to look for square roots of numbers is to start by factorising them.
In this example,
256
is obviously even, so divide it by
2
to find:
256
=
2
⋅
128
Then
128
is even, so divide that by
2
to find:
256
=
2
⋅
2
⋅
64
Keep on going until you find:
256
=
2
⋅
2
⋅

=

At this point it is clear that:
256
=
(
2
⋅

(

=

=
(

)

=

So
16
is a solution, but
−
16
is also a solution since:
(
−
16
)
2
=
(
−
16
)
⋅
(
−
16
)
=
256
