voi a,b la hai so tu nhien thoa man :a.b=20 va a<b.Khi do a+b co gia tri lon nhat la
tinh gia tri cua bieu thuc a+b biet rang a la so nguyen am lon nhat co 2 chu so b la so nguyen am nho nhat co 2 chu so
giup minh voi cam on
hai so nguyen duong x,y co tong la 51
a tim gia tri lon nhat cua x.y
b tim gia tri nho nhat cua tich x,y, biet rang x va y deu lon hon 1
so cac gia tri nguyen cua n thoa man A=3n+4/n-1 co gia tri nguyen la...
biết a b là một cặp số nguyên thỏa mãn (a+1)(b+2) = 3 khi do a.b lon nhat co gia tri la
tim cap a;b nguyen sao cho a,b lon nhat thoa man (a+1).(b+2)=3
tim cap a,b nguyen sao cho a,b lon nhat thoa man (a+1)(b+2)=3
CHO bieu thuc
B=17,58*43+57*17,58/293*A
a)tim gia tri cua bieu thuc Bkhi a=2
b)tinh gia tri a khi B=2
c)tim gia tri so tu nhien ad biet bieu thuc B co gia tri lon nhat ,gia tri lon do la bao nhieu
tim cap a;b nguyen sao cho a*b lon nhat
thoa man ( a+1 ) (b+2 )=3
