a+a*9-a*2=96
a*(1+9-2)=96
a*8=96
a=96:8
a=12
K mình nha.Good luck
a + a . 9 - a . 2 = 96
a . 7 + a = 96
a . 8 = 96
a = 96 : 8
a = 12
tim a,b€N .a+b=96 va UCLN cua a,B =6
tim phan so a/b biet:
a/b = 34/14 va a+b = 96, (a,b thuoc n sao)
tim 3 so tu nhien a,b,c nho nhat khac 0 sao cho 64×a=80×b=96×c
CHO S= 5+5^2+5^3+5^4+...+5^95+5^96
a.chung to s chia het cho 126
b. tim chu so tan cung cua s
11. tim nEn biet
a. 9<3^n be hon hoac bang 243
b. 9<3^n<27
c. 25 be hon hoac bang 5^n < 3125
Tim x
a) 1/9 * 34 * 3x = 37
b) 1/9 * 27x = 3x
c) 2x+2 - 2x = 96
d) 720 : [ 41 - ( 2x - 5) ] = 23 * 5
Tim 2 so tu nhien a,b biet tong cua chung bang 96 va UCLN cua chung bang 16 va a>b
Giai nhanh ho minh nhe!
biet : a + b = 96 va UCLN[ a,b ] = 6 [a>b]
1. a) tim 2 so tu nhien a,b (a,b>0);biet (a,b)=9;[a,b]=54
b) tim 2 so tu nhien a,b (a,b>0);biet a+b=42; [a,b]=72
cho a=-4, b=-9 . tim A biet A^2 = b.(a-c)-c.(a-b)
