0,04-10-8-2,3-1012 = 0,0410^8 - 2,310^12 = 410^6 - 2,310^12 = -2,296*10^12. Bu javob variantlar orasida yo'q, lekin javob variantiga yaqin. Tenglamani to'g'ri hal qilib, javobni topish mumkin.
m ning qanday qiymatida $\frac{9m+7}{6}$ ifodaning qiymati $11\frac{2}{3}$ ga teng bo'ladi?
m ning qanday qiymatida $\frac{9m+7}{6}$ ifodaning qiymati $11\frac{2}{3}$ ga teng bo'ladi?
Tenglamani $\frac{9m+7}{6}=11\frac{2}{3}$ hal qilib, $m$ uchun qiymatni topamiz.
$ \frac{9m+7}{6} = \frac{35}{3} $ $ 9m+7 = \frac{35}{3}*6 $ $ 9m+7 = 70 $ $ 9m = 63 $ $ m = 7 $
Agar n va m natural sonlar uchun $\frac{6n-4m}{n} = 1$ tenglik bajarilsa, $\frac{1}{n} + \frac{2}{m}$ ifodaning eng katta qiymatini toping.
Agar n va m natural sonlar uchun $\frac{6n-4m}{n} = 1$ tenglik bajarilsa, $\frac{1}{n} + \frac{2}{m}$ ifodaning eng katta qiymatini toping.
Tenglamani $\frac{6n-4m}{n} = 1$ soddalashtirib, $n$ va $m$ o'rtasidagi bog'lanishni topamiz. $ \frac{6n-4m}{n} = 1 $ $ 6n - 4m = n $ $ 5n = 4m $ $ n = \frac{4}{5}m $
$ \frac{1}{n} + \frac{2}{m} $ ifodasini $n$ o'rniga $\frac{4}{5}m$ qo'yib, ifodani soddalashtirib yozamiz. $ \frac{1}{n} + \frac{2}{m} = \frac{5}{4m} + \frac{2}{m} = \frac{13}{4m} $. $ m $ ning eng kichik qiymatini qo'yib (masalan, $m = 1$ ), ifodaning eng katta qiymatini topamiz. $ \frac{13}{4m} = \frac{13}{4}$.
Agar n va m natural sonlar uchun $n^2 - m^2 = 25$ tenglik bajarilsa, $n + 2m$ ifodaning qiymatini toping.
Agar n va m natural sonlar uchun $n^2 - m^2 = 25$ tenglik bajarilsa, $n + 2m$ ifodaning qiymatini toping.
