Question
Find the smallest natural number which when divided by
β4β, β6β and β15β, leaves a remainder β3β in each case.Solution
LCM of (4, 6 and 15) = 60 So, required number = 60 + 3 = 63
Equation 1: xΒ² - 180x + 8100 = 0
Equation 2: yΒ² - 170y + 7225 = 0
l). pΒ² - 26p + 153 = 0
ll).Β qΒ² - 17q + 72 = 0
How many values of x and y satisfy the equation 2x + 4y = 8 & 3x + 6y = 10.
Equation 1: xΒ² + 16x + 63 = 0
Equation 2: yΒ² + 10y + 21 = 0
I. (4x-5)3Β +Β 1/(4x-5)3Β = 2
II. 2[(y+1/y)2- 2]- 9(y+1/y)= -14
I. 5xΒ² = 19x β 12
II. 5yΒ² + 11y = 12
I. x2 – 10x + 21 = 0
II. y2 + 11y + 28 = 0
(i) 2xΒ² β x β 3 = 0
(ii) 2yΒ² β 6y + 4 = 0
I. 27xΒ² + 120x + 77 = 0
II. 56yΒ² + 117y + 36 = 0
I. 6 yΒ² + 11 y β 7= 0
II. 21 xΒ² + 5 x β 6 = 0
