Đáp án: (x+1/4)^4 . (1/8)^2 = (1/4)^3 ⇒ (x+1/2)^8 . (1/2)^6 = (1/2)^6 ⇒ (x+1/2)^8 = 1 ⇒ x+1/2 = 1 ⇒ x = 1-1/2 ⇒x=1/2 Bình luận
(x+1/4)^4 . (1/8)^2 = (1/4)^3 ⇒ (x+1/2)^8 . (1/2)^6 = (1/2)^6 ⇒ (x+1/2)^8 = 1 ⇒ x+1/2 = 1 ⇒ x = 1/2 Bình luận
Đáp án:
(x+1/4)^4 . (1/8)^2 = (1/4)^3
⇒ (x+1/2)^8 . (1/2)^6 = (1/2)^6
⇒ (x+1/2)^8 = 1
⇒ x+1/2 = 1
⇒ x = 1-1/2
⇒x=1/2
(x+1/4)^4 . (1/8)^2 = (1/4)^3
⇒ (x+1/2)^8 . (1/2)^6 = (1/2)^6
⇒ (x+1/2)^8 = 1
⇒ x+1/2 = 1
⇒ x = 1/2
