Tolong bantu no 4a.. terimakasihh

⁴log² x² - ⁴log x^10 + 4 = 0
⁴log² x² - ⁴log (x²)^5 + 4 = 0
⁴log² x² - 5 . ⁴log x² + 4 = 0
(⁴log x² - 1)(⁴log x² - 4) = 0

Pembuat nol
⁴log x² - 1 = 0
⁴log x² = 1
x² = 4
x = 2 atau x = -2

⁴log x² - 4 = 0
⁴log x² = 4
x² = 4^4
x = 16 atau x = -16

HP = {-16 , -2 , 2 , 16} ✔
