Mark as BRAINLIEST

Step-by-step EXPLANATION:

so from the Q the total sum of age of 15 students is 135×15 MONTHS

let the age of teacher is X months , then the new sum is 2025 + X months

& is equal to 16 × 148.5 which is equal to 2376 on equating these TWO , X will be 351 which MEANS the age of the teacher is 29years 3months

X = 3 - 2√2 ----( 1 )

1/x = 1/( 3 - 2√2 )

= ( 3 + 2√2 ) / [1/x = 1/( 3 - 2√2

= ( 3 + 2√2 ) / [ 3² - ( 2√2 )² ]

= ( 3 + 2√2 ) / ( 9 - 8 )

= 3 + 2√2 ----( 2 )

x + 1/x = 3 - 2√2 + 3 + 2√2

= 6 ------( 3 )

x - 1/x = 3 - 2√2 - ( 3 + 2√2 )

= 3 - 2√2 - 3 - 2√2

= - 4√2 ---- ( 4 )

Now ,

x² - 1/x² = ( x + 1/x ) ( x - 1/x )

= 6 × ( - 4√2 )

[ From ( 3 ) and ( 4 ) ]

= - 24√2

Step-by-step explanation:

0 is the FIRST and SMALLEST WHOLE NUMBER

Answer:

Answer

Given number =23

By using COLUMN method we have,

∴a=2 and B=3

a

2

(2×a×b) b

2

4 12 9

+1 +0

=5 =12

∴(23)

2

=529

Steps involved in solving column method:

Step 1: Make three columns headed by a

2

,2×a×b and b

2

respectively. Write the values of a

2

,2×a×b and b

2

in columns respectively.

Step 2: In third column underline the unit digits of b

2

i.e 9 and carry the tens digit of it i.e. 0 to the SECOND column and add it to the value of second column is 2×a×b and it will remains 12 if it added to 0.

Step 3: In column second, underline the unit digit of the number obtained in second step i.e. 2 and carry over the ten digit of it to first column and add it to the value of a

2

i.e. 4+1=5

Step 4: Now underline the number obtained in third step in first column i.e. 5. The underlined digits give the required square number.
