Tolong bantu bagian D yaa... makasihh

Answer 1

Verified answer

4' log ( 4-x^2) = 4' log(x^2-5)

Syarat 1
( 4-x^2) >0
( 2-x) (2+x)>0

2-x>0《 atau x>-2

2>x=>x<2
Hp {-2
SYARAT 2
(x^2-5) >0
( x+5) (x-5)>0

Syarat 3
( 4-x^2) = (x^2-5)
4+5 = x^2+x^2
9 = 2x^2
9/2 = x^2
Akar 9/2 = x
X1 = 3 (akar 1/2)
X2 = -3 ( akar 1/2)
