14.

Find the least square number which is exactly divisibleeach of thenumber 8, 9, 10 and 15.

Answer»

Solution :

$\bigstar$ Firstly, we get L.C.M of each number 8,9,10 & 15 ;

$\begin{array}{r|l} <klux>2</klux> & 8,9,10,15 \\ \cline{2-2} 2 & <klux>4</klux>,9,5,15 \\ \cline{2-2} 2 & 2,9,5,15 \\ \cline{2-2} <klux>3</klux>& 1,9,5,15 \\ \cline{2-2} 3 & 1,3,5,5 \\ \cline{2-2} 5& 1,1,5,5 \\ \cline{2-2} & 1,1,1,1 \end{array}}$

Prime factorization = 2 × 2 × 2 × 3 × 3 × 5

We should MULTIPLY by 2 & 5 to get complete square number.

Thus;

⇒ The required square number = 2² × 2² × 3² × 5²

⇒ The required square number = 4 × 4 × 9 × 25

⇒ The required square number = 3600

Answer»

${\huge{\sf{\green{\underline{\underline{Solution:-}}}}}}$

━━━━━━━━━━━━━━━━━━━━━

✰ Given sum of two numbers = -24

let the first number be X,

so the equation according to the question will be,

x + (-12) = - 24

x - 12 = - 24

x = -24 + 12

x = - 12

✰ Hence, option (a) - 12 is CORRECT answer.

✰ Then, the two numbers whose sum is - 24 are : -12 and - 12

If 2 root 3 + 3 root 2 / 2 root 3 - 3 root = a+b root 6 , then find the value of a and b plz.......answer this fast...........i have exam tmrow....plz

Answer»

We've been GIVEN that;

$\Longrightarrow \sf \dfrac{2\sqrt{3} + 3\sqrt{2}}{2\sqrt{3} - 3\sqrt{2}} = a + <klux>B</klux>\sqrt{6}$

LHS;

$\Longrightarrow \sf \dfrac{2\sqrt{3} + 3\sqrt{2}}{2\sqrt{3} - 3\sqrt{2}}$

$\Longrightarrow \sf \dfrac{2\sqrt{3} + 3\sqrt{2}}{2\sqrt{3} - 3\sqrt{2}} \times \dfrac{2\sqrt{3} + 3\sqrt{2}}{2\sqrt{3} + 3\sqrt{2}}$

$\Longrightarrow \sf \dfrac{\Big(2\sqrt{3} + 3\sqrt{2}\Big)^2}{\Big(2\sqrt{3}\Big)^2 - \Big(3\sqrt{2}\Big)^2}$

$\Longrightarrow \sf \dfrac{4(3) + 9(2) + 12\sqrt{6}}{4(3) - 9(2)}$

$\Longrightarrow \sf \dfrac{12 + 18 + 12\sqrt{6}}{12 - 18}$

$\Longrightarrow \sf \dfrac{30 + 12\sqrt{6}}{-6}$

$\Longrightarrow \sf \dfrac{6(5 + 2\sqrt{6})}{-6}$

$\Longrightarrow \sf \dfrac{5 + 2\sqrt{6}}{-<klux>1</klux>}$

$\Longrightarrow \sf \dfrac{5}{-1} + \dfrac{2\sqrt{6}}{-1}$

⇒ a = 5/-1

⇒ b = (2√6)/-1
