If a and b are rational numbers, find their value if :3 √5+ √3/√5− √3 = a + b√15 |
|
Answer» Answer: MARK me as brainlist Step-by-step explanation: It is given that − 3
5 + 3
=a+b
SIMPLIFY the term on the L.H.S. by rationalizing, 5 − 3
5 + 3
× 5 + 3
5 + 3
= ( 5 ) 2 −( 3 ) 2
( 5 + 3 ) 2
= 5−3 ( 5 ) 2 +( 3 ) 2 +2 5
3
= 2 5+3+2 15
= 2 8+2 15
=4+ 15
Now, 4+ 15 =a+b 15
⇒a=4 and b=1 |

If =a 2+√3 then find the Value of a2 +1/a2 |
Answer» EXPLANATION.As we know that, We can write equation as, ⇒ 1/a = 1/(2 + √3). Now, RATIONALIZE the equation, we get. ⇒ 1/a = 1/(2 + √3) x (2 - √3)/(2 - √3). ⇒ 1/a = (2 - √3)/[(2)² - (√3)²]. ⇒ 1/a = (2 - √3)/[4 - 3]. ⇒ 1/a = (2 - √3)/1 = 2 - √3. To find : ⇒ a² + 1/a². ⇒ a² = (2 + √3)². ⇒ a² = 4 + 3 + 4√3. ⇒ a² = 7 + 4√3. ⇒ 1/a² = (2 - √3)². ⇒ 1/a² = 4 + 3 - 4√3. ⇒ 1/a² = 7 - 4√3. ⇒ (a² + 1/a²) = [(7 + 4√3) + (7 - 4√3]. ⇒ (a² + 1/a²) = [7 + 4√3 + 7 - 4√3]. ⇒ (a² + 1/a²) = 14. |

In the figure , ABCD is a parallelogram. P, Q , R , S are the midpoint of the sides of the parallelogram . Then prove that PQ = RS and QR = PS |
|
Answer» Answer: Step-by-step explanation: Given : - ABCD is a parallelogram P , Q , R & S are the mid points of the sides AB , BC , CD , DA Required to PROVE : - PQ = RS QR = PS Theorem used : - Mid point theorem This states that ; The line segments joining the midpoints of the two sides of the triangle is parallel to the third side and also half of the third side . Solution : -ABCD is a parallelogram P , Q , R & S are the mid points of the sides AB , BC , CD , DA Here, AC is a DIAGONAL . Consider ∆ ABC & ∆ ADC In ∆ ABC & ∆ ADC . => AC = AC ( side ) [ Reason : Common side ] => AB = CD ( side ) [ Reason : In a parallelogram, opposite sides are equal ] => AD = BC ( side ) [ Reason : In a parallelogram , opposite angles are equal ] By using S.S.S. Congruency rule ∆ ABC ∆ADC However, Similarly, if you want to write easily you can write that in a parallelogram a diagonal divides it into 2 Congruency triangles . so ∆ ABC ∆ADC This implies ; PQ = ½ AC RS = ½ AC [ Reason : Mid point theorem ] SINCE, RHS part is equal . Let's equate the LHS part . Hence, PQ = RS Similarly, Construction : -Draw the diagonal BD in the ||gm PQRS . Consider ∆ BCD & ∆ BAD In ∆ BCD & ∆ BAD => BD = BD ( side ) [ Reason : Common side ] => BC = AD ( side ) [ Reason : Opposite sides are equal ] => CD = AB ( side ) [ Reason : Opposite sides are equal ] By using S.S.S. Congruency rule ; ∆ BCD ∆BAD This implies ; QR = ½ BD QR = ½ BD PS = ½ BD [ Reason : Mid point theorem ] Since, RHS part is equal . Let's equate the LHS part Hence, QR = PS Hence Proved Hope my answer helps youMark me as brainliest |
