the average age of 15 students is 11yr and 3 months which is increased by 1 year and 3/2 months when the age of teacher is included find the age of teacher in years and months​

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

3.

If x = 3 - 2√2 , find x² + 1/x²​

Answer»

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

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
