Find the hcf and lcm of a2 b4 c and a4 b5 c7 Please i need step by step explanation |
Answer» Full explanationThe following method is suggested for finding the HCF of several polynomials (a) Write each polynomial as a product of prime factors. (B) The HCF is the product obtained by taking each factor to the lowest power to which it occurs in both the polynomials. For example, The HCF of 23 32 (x - y)3(x + 2y)2; 2233 (x - y)2 (x + 2y)3 and 32(x - y)2 (x + 2y) is 32(x - y)2 (x + 2y). Note- Two or more polynomials are relatively prime if their HCF is 1. LCM of Polynomials The LCM of two or more given polynomials is the polynomial of lowest DEGREE and smallest numerical coefficients for which each of the given polynomials will be its factor. Method to find LCM of polynomial The following PROCEDURE is suggested for determining the LCM of several polynomials. (a) Write each polynomial as a product of prime factors. (b) The LCM is the product obtained by taking each factor to the HIGHEST power to which it occurs. For example, The LCM of 2332 (x — y)3(x + 2y)2; 2233(x — y)2 (x + 2y)3; 32(x — y)2(x + 2y) is 2333 (X — y)3 (x + 2y)3. Example1. Find the HCF and LCM of (I) 9X4y2 and 12X3y3 (ii) 6x — 6y and 4x2 — 4y2. Sol. (i) 9x4y2 = 32 x x4 x y2 and 12X3y3 = 22x 3 x X3 x y3. HCF = 3x3y2 and LCM = 32 x 22 X x4 X y3 =36X4y3 So, HCF = 3x3y2, LCM = 36x4y3 (ii) 6x — 6y = 2 x 3 x (x — y) and 4x2 — 4y2 = 22(x2— y2) = 22 x (x + y) (x — y) HCF = 2(x — y) and LCM = 22x 3 x (x — y)(x + y) = 12(x — y) (x + y). So, HCF = 2(x — y), LCM = 12(x + y) (x — y). Special Products The following are some of the products which occur frequently in mathematics and the student should become familiar with them as soon as possible. Product of a monomial and a binomial a (c + d) = ac + ad. Product of the sum and the difference of two terms (a + b)(a — b) = a2 — b2. Square of a binomial (a + b)2 = a2 + 2ab + b2. (a — b)2 = a2 — 2ab + b2 Product of two binomials (x + a)(x + b) = x2 + (a + b)x + ab. (ax + b)(cx + d) = acx2 + (ad + bc)x + bd. ,(a+b)(c+d)=ac+bc+ad+bd. Cube of a binomial (a + b)3 = a3 + 3a2b + 3ab2 + b3. (a — b)3 = a3 — 3a2b + 3ab2 — b3. Square of a trinomial (a + b + c)2 = a2 + b2 + c2 + 2(ab + ac + bc). Products that give answers of the form a n ± bn. It may be verified by multiplication that (a — b)(a2 + ab + b2) = a3 — b3 (a — b)(a3 + a2b + ab2 + b3) = a4 — b4 (a — b)(a4 + a3b + a2b2 + ab3 + b4) = a5 — b5 |

LET'S PRACTICE 1.41. State which of the following statements are true or false ? Also, justify by giving an example.(i) The collection of integers obey closure property for division.(ii) The collection of integers is commutative under multiplication.(iii) The collection of integers is commutative under division.(iv) The distributive property of '÷' over '+' holds good in case of integers.(v) Division by 1 is undefined.(vi) Division of any integer by O always gives 0.SIG QUR NUMBERS |
|
Answer» Answer: Integers are commutative under addition when any two integers are added irrespective of their order, the sum remains the same. a+b =b+a The sum of two INTEGER numbers is ALWAYS the same. This means that integer numbers follow the commutative property. Let’s see the FOLLOWING examples: 15 + 20 =35; 20 +15=35 -10 + (-5) = -15; -5 + (-10) = -15 The above examples prove that the addition of integers is commutative. The commutative property for Subtraction: Is the case true with subtractions? Are subtractions also commutative? The following examples will let US know this: 5-(-3) = +8 -3-5 = -8 This brings us to the conclusion that subtractions of integers are not commutative. Therefore, a-b ≠ b-a Commutative Property of Division This property does not apply to divisions between integers. This means that a÷b ≠b÷a Option A is correct |

|
Answer» Answer: ∠x = 70 ° and ∠ y = 80°Step-by-step EXPLANATION: we know that if two lines are parallel then the ALTERNATE opp angles are equal so ∠ QPR= ∠PRT ===> ∠x = 70 ° now , QPR is forming a triangle and angle SUM property of triangle SAYS that sum of all interior angles of triangle is 180 ° so, 30° + 70° + ∠y = 180° ∠ y = 180° - 100° = 80° |
