square root of 196
Step-by-step explanation:
ANSWER= ♡
Explanation:
The square root of 196 in math symbology looks like this:
√
196
So what does it mean?
The square root operation is the opposite of squaring something. For instance, 3 squared is 9 and the square root of 9 is 3:
3
2
=
9
√
9
=
3
And if I write something like this:
√
3
2
that is both operations at once, the square and the square root cancel each other out and the answer is 3:
√
3
2
=
3
Back to
√
196
. Is there a number we can square to arrive at 196? The answer is yes - 14. There are two ways to figure this out - one is to simply remember it (I used this way because I'm a math geek and I remember stuff like this...) and the other is to work it out by breaking down the 196 into its factors. Like this:
√
196
=
√
2
⋅
98
=
√
2
⋅
2
⋅
49
=
√
2
⋅
2
⋅
7
⋅
7
=
√
14
⋅
14
=
√
14
2
And now that we know that
√
196
=
14
2
, we can now say:
√
196
=
√
14
2
=
14
