cho (a,b)=1 tìm (a+b, a-b)
please help me :(((
Theo đề a,b là nguyên tố cùng nhau. Gọi ƯCLN của (a+b, a-b)=d
Ta có:
+ B chia hết cho d vào a-b chia hết cho d
+ Cộng vế theo vế có 2a chia hết cho d
⇒ a chia hết cho d ( hoặc 2 chia hết cho d nên d=1;2)
+ Trừ vế theo vế ta có 2a chia hết cho d
Vậy d là ước chung của a và b àm a, b là nguyên tố cùng nhau nên
UCLN (a;b) =d=1 vậy (a+b, a-b)=d=1 (a+b, a-b nguyên tố cùng nhau)
Tick hộ nha 😍

we have:
A. Tìm số thực x biết
24-16(x-1/2)=23
help me ! help me! help me! help me!
24 - 16(x - 1/2) = 23
=> 16(x - 1/2) = 24 - 23
=> 16(x - 1/2) = 1
=> x - 1/2 = 1/16
=> x = 1/16 + 1/2
=> x = 9/16

\(24-16(x-\frac{1}{2})=23\)
\(16(x-\frac{1}{2})=24-23\)
\(16(x-\frac{1}{2})=1\)
\(x-\frac{1}{2}=\frac{1}{16}\)
\(x=\frac{1}{16}+\frac{1}{2}\)
\(x=\frac{9}{16}\)
Vậy số thực x cần tìm là \(\frac{9}{16}\)
