Answer»

Step-by-step explanation:

For this, we use the method called prime factorization.

Step 1 :

Find the prime factors of the given number.

Step 2 :

To find the square root, we have to group the factors as pairs.

Step 3 :

By grouping the factors as pairs, we MAY find some of the numbers which are being extra.These are the required numbers to be divided in order make the given number as a perfect square.

Example 1 :

Find the LEAST number by which 384 must be divided to make it a perfect square.

Solution :

Step 1 :

Let us find the prime factors of 384 using the method prime factorization.

Step 2 :

384 = 2 ⋅ 2 ⋅ 2 ⋅ 2 ⋅ 2 ⋅ 2 ⋅ 2 ⋅ 3

Step 3 :

‘3’ and '2' remains without a pair.

Hence, 384 must be divided by 6 to make it a perfect square.

Find the capacity in litres of conicalvessel withradius 7cm slant height 25 cm​

Answer»

GIVEN:-

RADIUS => 7cm

Slant height => 25cm

VOLUME of CONE => 1/3 πr²h

we know that ,

Slant height => √(h²+r²)

25 = √(h²+49)

625 = h²+49

h²= 625-49

h²=576

h=√576

h=24 cm

Now,

volume => 1/3 *22/7*49*24

=>1232 cm³

Converting into litre :-

Answer»

Step-by-step explanation:

There are 136 apples,170 mangoes and 255 oranges . These are to be arranged in heaps containing the same number of fruits . Find the greatest number of fruits possible in each heap. How many heaps are formed

We need to find HCF of

136 , 170 & 255

136 = 2 * 2 * 2 * 17

170 = 2 * 5 * 17

255 = 3 * 5 * 17

HCF = 17

the greatest number of fruits possible in each heap = 17

Heaps of APPLE = 136/17 = 8

Heaps of Mangoes = 170/17 = 10

Heaps of Oranges = 255/17 = 15

Total Number of Heaps = 8 + 10 + 15 = 33

Question : -

\sf{ \sqrt[4]{81} - 8 \sqrt[3]{216} + 15 \sqrt[5]{32} + \sqrt{225} }

ANSWER

Given : -

\sf{ \sqrt[4]{81} - 8 \sqrt[3]{216} + 15 \sqrt[5]{32} + \sqrt{225} }

Required to find : -

  • Value of

\sf{ \sqrt[4]{81} - 8 \sqrt[3]{216} + 15 \sqrt[5]{32} + \sqrt{225} }

Solution : -

\sf \to \sqrt[4]{81} - 8 \sqrt[3]{216} + 15 \sqrt[5]{32} + \sqrt{225} \\ \\ \rm we \: know \: that \\ \\ \to \sf \sqrt[a]{x} = {x}^{ \frac{1}{a} } \\ \\ \to \sf (81 {)}^{ \frac{1}{4} } - 8(216 {)}^{ \frac{1}{ 3} } + 15(32 {)}^{ \frac{1}{5} } + (225 {)}^{ \frac{1}{2} } \\ \\ \to \sf ( {3}^{4} {)}^{ \frac{1}{4} } - 8( {6}^{3} {)}^{ \frac{1}{ 3} } + 15( {2}^{5} {)}^{ \frac{1}{5} } + ( {15}^{2} {)}^{ \frac{1}{2} } \\ \\ \rm \because ( {a}^{m} {)}^{n} = {a}^{mn} \\ \\ \to \sf {3}^{ \frac{4}{4} } - 8( {6}^{ \frac{3}{3} } ) + 15( {2}^{ \frac{5}{5} } ) + {15}^{ \frac{2}{2} } \\ \\ \to \to \sf 3 - 8(6) + 15(2) + 15 \\ \\ \to 3 - 48 + 30 + 15 \\ \\ \to 48 - 48 \\ \\ \to 0

Question : -

If x = 3 + √8 , then the value of ( x² + 1/x² )

Answer

Given : -

x = 3 + √8

Required to find : -

  • value of ( x² + 1/x² ) ?

Solution : -

x = 3 + √8

➞ x² =

➞ ( 3 + √8 )²

Using the identity ;

  • ( a + b )² = a² + b² + 2ab

➞ ( 3 + √8 )² =

➞ ( 3 )² + ( √8 )² + 2 ( 3 ) ( √8 )

➞ 9 + 8 + 6√8

➞ 17 + 6√8

1/x² =

➞ 1/ 17 + 6√8

Here we NEED to rationalize the denominator .

➞ Rationalising factor = 17 - 6√8

MULTIPLY the numerator and denominator with 17 - 6√8

➞ 1/17 + 6√8 x 17 - 6√8/17 - 6√8

➞ 17 - 6√8/( 17 )² - ( 6√8 )²

➞ 17 - 6√8/289 - 288

➞ 17 - 6√8/1

➞ 17 - 6√8

value of x² + 1/x² is ;

➞ 17 + 6√8 + 17 - 6√18

➞ 17 + 17

➞ 34

\rule{400}{4}

Question : -

A rational NUMBER between √2 and √3

Answer

Given : -

√2 & √3

Required to find : -

  • A rational number in between them ?

Formula used : -

A rational number between any 2 rational numbers a & b is a+b/2

SOLUTION : -

A rational number √2 and √3 is ;

Using the formula ,

A rational number between any 2 rational numbers a & b is a+b/2

➞ a + b/2

➞ (√2 + √3)/2

Hence,

➞ The rational number between √2 and √3 is (√2 +√3)/2
