(10+2x).6^7 = 6^9 10+2x = 6^9 : 6^7 10+2x = 6^2 10+2x = 36 2x = 36-10 2x = 26 x = 13 71-(33+x)=26 33+x=71-26 33+x=45 x=45-33 x=12 100-(4x+1)=1976^0 .3 100-(4x+1)=1.3 100-(4x+1)=3 4x+1=100-3 4x+1=97 4x=96 x=96:4 x=24 Mk gửi ạ Trả lời
(10 + 2x).6^7 =6^9 (10 + 2x) = 6^9 : 6^7 10 + 2x = 6^2 10 + 2x = 36 2x = 36 – 10 2x = 26 x = 26 : 2 x = 13 Vậy x = 13 71 – (33 + x)=26 33 + x = 71 – 26 33 + x = 45 x = 45 – 33 x = 12 Vậy x = 12 100 – (4x + 1)=1976^0 . 3 100 – (4x + 1)= 1 .3 100 – (4x + 1)= 3 4x + 1 = 100 – 3 4x + 1 = 97 4x = 97 – 1 4x = 96 x = 96 : 4 x = 24 Vậy x = 24 Trả lời
