Question 3:An army contingent of 616 members is to march behind an army bandof 32 members in a parade. The two groups are to march in the samenumber of columns. What is the maximum number of columns inwhich they can march? |
|
Answer» Answer: the answer is 8 Step-by-step explanation: To get the maximum number COLUMN here we always find HCF and for minimum number we find LCM So can use Euclid’s algorithm to find the HCF. Here 616> 32 so always divide greater number with smaller one When we divide 616 by 32 we get QUOTIENT 19 and remainder 8 So we can write it as 616 = 32 X 19 + 8 Now divide 32 by 8 we get quotient 4 and no remainder So we can write it as 32 = 8 x 4 + 0 As there are no remainder so our HCF will 8 So that maximum number of COLUMNS in which they can march is 8. |

Can a number 4^n, n being a natural number, end with the digit 5? Give reason. |
|
Answer» Answer: no,it will not end with 5 Step-by-step EXPLANATION: first check with what all can 4^n end u can see that 4^1=4 4^2=16 4^3=64 4^4=256 4^5=1024 4^6=4096 so after two terms the ending number is repeating this is called cyclicity we can see that 4^n where n is odd ENDS with 4 and where n is EVEN ends with 6 if n is 0 of couurse u know that it ends with 1 therefore it will not end with 5 |

if alpha, beta are the roots of the quadratic equation ax^2+bx+c=0 find a quadratic equation whose roots are alpha^2+beta^2 and aloha^-2+beta^-2 |
|
Answer» Answer: a²c²x² - ( b^2 - 2ac )( a^2 + c^2 )x + ( b^2 - 2ac )^2 = 0 Step-by-step explanation: Eq. is ax^2 + bx + c = 0 ⇒ x^2 - (-b/a)x + (c/a) = 0. Quadratic equation written in the form of x^2 - Sx + P = 0 represent S as sum of roots and P as the product of their roots. So, here if α and β are roots. S = α + β = - b / a P = αβ = c / a Therefore, α^2 + β^2 = (α+β)² - 2αβ = ( - b / a )^2 - 2( c / a ) = b^2 / a^2 - 2c / a = ( b^2 - 2ac ) / a^2 1 / α^2 + 1 / β^2 = ( α^2 + β^2 ) / ( αβ )^2 = {(b^2 - 2ac)/a^2}/{(c/a)^2} = ( b^2 - 2ac ) / c^2 Here, we are asked for the equation with roots ( b^2 - 2ac ) / a^2 and ( b^2 - 2ac ) / c^2. So, if that equation is x^2 - Kx + L = 0. So, K is the sum of roots and L is the product of roots. This means : K = ( b^2 - 2ac ) / a^2 + ( b^2 - 2ac ) / c^2 K = ( b^2 - 2ac )( a^2 + c^2 ) / ( ac )^2 And, L = ( b^2 - 2ac )/a^2 * ( b^2 - 2ac )/c^2 L = ( b^2 - 2ac )^2 / ( ac )^2
HENCE the REQUIRED equation is : x^2 - x( b^2 - 2ac )( a^2 + c^2 )/(ac)^2 + ( b^2 - 2ac )^2/(ac)^2 = 0 ⇒ a²c²x² - ( b^2 - 2ac )( a^2 + c^2 )x + ( b^2 - 2ac )^2 = 0 Hence the required equation is a²c²x² - ( b^2 - 2ac )( a^2 + c^2 )x + ( b^2 - 2ac )^2 = 0. |
