Answer:
44, 55 and 66.
Step-by-step explanation:
I think you mean the sum of the SECOND and 55. It makes no sense otherwise, if the numbers are integers.
The 3 numbers can be written as 4x, 5x and 6x . So we have the equation:
4x + 6x = 5x + 55
5x = 55
x = 11
So the numbers are 44, 55 and 66.
Answer:
(i) 5 + 2√6
(ii) 1 - 2√6
Step-by-step explanation:
(i) (√3+√2)(√3+√2)
⇒ √3(√3+√2) + √2(√3+√2)
or
⇒ (√3)² + (√3 × √2) + ( √2 ×√3 ) + ( √2 × √2 )
or
⇒ 3 + √6 + √6 + 2
or
⇒ 5 + 2√6
(ii) (√3+√2)(√3-√2)
⇒ √3(√3-√2) + √2(√3-√2)
or
⇒ ( √3 × √3 ) - ( √3 × √2) + ( √2 × √3 ) - ( √2 ×√2)
or
⇒ ( 3 ) - ( √6 ) + ( √6 ) - ( 2 )
or
⇒ 1 - 2√6
