The square root of 17 would be 4.12 approximatly.
What is a perfect square?
A** perfect square **is a number system that can be expressed as the
**square **of a given number from the same system.
A** Perfect square** are those **integers **whose square root is an integer.
Let x-a be the closest **perfect square **less than x,
and let x+b be the closest **perfect square more than x, then we get: x-a < x < x+b (no perfect square **in between x-a and x+b, except possibly x itself).
Then, we get:
x − a ​ < x ​ < x + b ​
WE have to solve X squared =17
We have to take the square root of 17
So it would be 4.123105626 approximatly 4.12 .
Therefore, the square root of 17 would be 4.12 approximatly.

To solve X 2 = 17 , take the square root of both sides to get X = 17 ​ and X = − 17 ​ . This results in approximately X ≈ 4.12 and X ≈ − 4.12 .

Jawab:[tex]\boxed{\{2\}}[/tex]Penjelasan dengan langkah-langkah:Diberikan persamaan:[tex]|x + 1| + 2x = 7[/tex]Kita diminta mencari himpunan penyelesaian x.Karena ada |x + 1| kita perlu mempertimbangkan dua kasus:Kasus 1: [tex]x + 1 \geq 0 \implies x \geq -1[/tex]Kasus 2: [tex]x + 1 < 0 \implies x < -1[/tex]Kasus 1: [tex]x \geq -1[/tex][tex]|x + 1| = x + 1[/tex][tex]x + 1 + 2x = 73x + 1 = 73x = 6 \implies x = 2[/tex]x=2 memenuhi syarat [tex]$x \geq -1$[/tex]. Ya , karena [tex]$2 \geq -1$[/tex].Kasus 2: [tex]x < -1[/tex][tex]|x + 1| = -(x + 1) = -x - 1(-x - 1) + 2x = 7-x - 1 + 2x = 7x - 1 = 7x = 8[/tex]x=8 memenuhi syarat [tex]x < -1[/tex]? Tidak, karena 8 tidak kurang dari -1.Hanya solusi x=2 yang memenuhi persamaan dan kondisi.Jadi, himpunan penyelesaian:[tex]\boxed{\{2\}}[/tex]
