Show that: (p¼- q¼)(p¼ + q¼)(√P+√q)= p-q.

Irina18 [472]

Answer:

Step-by-step explanation:

let p¼ = a, q¼ = b

L.H.S. = (a - b)(a + b)(a² + b²) = (a² - b²)(a² + b²) = (a²)² - (b²)² = p - q = R.H.S.

Find x.<br> A. 21(route)2<br> B. 7<br> C.21(route)3/2<br> D. 21(route)2/2

Lynna [10]

Answer:

Option (D)

Step-by-step explanation:

By applying Sine rule in the right ΔABD,

Sin(A) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

Sin(60)° = $\frac{\text{BD}}{\text{AB}}$

$\frac{\sqrt{3}}{2}=\frac{\text{BD}}{7\sqrt{3}}$

BD = $7\sqrt{3}\times \frac{\sqrt{3} }{2}$

= $\frac{21}{2}$

Now by applying Cosine rule in the right ΔBDC,

Cos(45)° = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$\frac{1}{\sqrt{2}}=\frac{\frac{21}{2}}{x}$

x = $\frac{21}{2}\times \sqrt{2}$

x = $\frac{21\sqrt{2}}{2}$

Therefore, Option (D) is the correct option.
