135 and 2231l) 867 and 235is of the form 6q + 1 , or 6q + 3, or 6q + 5, where q istheow that any positive odd integer2.nteger |
|
Answer» Let a be the positive odd integer which when divided by 6 gives q as quotient and r as remainder. according to Euclid's division lemmaa=bq+r a=6q+r where , a=0,1,2,3,4,5then,a=6qora=6q+1ora=6q+2ora=6q+3ora=6q+4ora=6q+5 but here,a=6q+1 & a=6q+3 & a=6q+5 are odd. |

Answer» Let a be an arbitrary positive integer.Then, by Euclid ’s divisions Algorithm, corresponding to the positive integers a and 5, there exist non-negative integers m and r such thata = 5m + r, where 0 ≤ r < 5⇒ a2= (5m + r2) = 25mr + r2+ 10mr [∵(a+b)2= a2+ 2ab + b2]⇒ a2= 5(5m2+ 2mr) + r2...(i)where, 0 ≤ r < 5 Case I When r = 0, then putting r = 0 in Eq.(i), we geta2= 5(5m2) = 5qwhere, q = 5m2is an integer. Case II When r = 1, then putting r = 1 is Eq.(i), we geta2= 5(5m2+ 2m) + 1⇒ q = 5q + 1where,q = (5m2+ 2m) is an integer. Case III When r = 2,then putting r = 2 in eq.(i),we geta2= 5(5m2+ 4m) + 4 = 5q + 4where, q = (5m2+ 4m) is an integer. Case IV When r = 3, then putting r = 3 in Eq.(i), we geta2= 5(5m2+ 6m) + 9 = 5 (5m2+ 6m) + 5 + 4= 5(5m2+ 6m + 1) + 4 = 5q + 4where, q = (5m2+ 8m + 3) is an integer. Case V When r = 4, then putting r = 4 in Eq.(i), we geta2= 5(5m2+ 8m) + 16 = 5 (5m2+ 8m) + 15 + 1⇒ a2= 5(5m2+ 8m + 3) + 1 = 5q + 1where, q = (5m2+ 8m + 3) is an integer. Hence, the square of any positive integer cannot be of the form 5q + 2 or 5q + 3 for any integer q. Like my answer if you find it useful! |

construct a angle of 75 degree |
|
Answer» The following steps are carried out to construct 75 degree-angle.Step 1: Draw a ray with end point A and BStep 2: With A as center and any radius, draw an arc cutting the ray at point C using a compassStep 3: With C as center and the same radius, draw an arc cutting the arc drawn at D.Step 4: With D as center and the same radius, draw an arc again intersecting the previously drawn arc at E.Step 5: Now, take any radius and draw two arcs with D and E as centers. Let these two arcs intersect at a point F.Step 6: Join AF ∠FAB obtained is the angle of measure of 90 degree.Step 7:The line AF intersect the arc at the point named as GStep 8: With G and D as center draw an arc with radius more than half of the measurement (GD).The arc intersect at the point P.Step 9: Join the point P and A.∠PAB obtained is the angle of measurement 75 degree. |

Answer» The given equation is 2x⁴ -5x²+3 =0 let x² = t so the equation becomes 2t²-5t+3 = 0=> 2t²-3t-2t+3 =0 => t(2t-3) -1(2t-3) = 0=> (t-1)(2t-3) = 0 so the value of t = 1, or t = 3/2but t = x² = 1, 3/2 so x can be = ±1 , ±√3/√2 2) 2x-3/x = 1 => 2x²-x-3 = 0 => 2x²-3x+2x-3 = 0 => x(2x-3)+1(2x-3) = 0 => (2x-3)(x+1) = 0 so ,x = 3/2, -1. |
