$lim_{x to 3} frac{9- x^{2}}{ 4 - sqrt{ x^{2} +7}}$

$lim_{x to 3} frac{9- x^{2}}{ 4 - sqrt{ x^{2} +7}}* frac{4 + sqrt{ x^{2} +7}}{4 + sqrt{ x^{2} +7}}$

$lim_{x to 3} frac{(9- x^{2})(4 + sqrt{ x^{2} +7})}{16 - x^{2} -7}$

$lim_{x to 3} frac{(9- x^{2})(4 + sqrt{ x^{2} +7})}{9 - x^{2}}$

$lim_{x to 3} (4 + sqrt{ x^{2} +7})$

$= (4 + sqrt{ 3^{2} +7})$

$= (4 + sqrt{ 9 +7})$

$= 4 + sqrt{ 16}$

$= 4 + 4$

$= 8$

Kalau nggak salah,
Jika x = 3
9-x^2 per
4- akar dari x+1

= 9-(3)^2 per 4 – akar dari 3+1

= 9-9 per 4 – akar dari 4

= 0 per 4 – 2

= 0 per 2

= 0
