Answer:(6) (1/3)^2 (2/3)^4
(2)
Step-by-step explanation: Each arrangement has a probability (1/3)^2 (2/3)^4 so our final answer we multiply this probability by the number of possible arrangements
= (7a + 2b)(7a + 2b)
= (7a +2b)^2
The multiplicative inverse for √2-i = 1/(√2+1) and The multiplicative inverse is √2+1 = 1/(√2-1)

Given Data
- First expression = √2+i
- Second expression = √2-i
For√2+i
the real part is is √2 and the imaginary part is i
The multiplicative inverse is √2+1 = 1/(√2-1)
rationalising the denominator we have
= 1/√2-1 * √2-1/√2-1
= √2-1/(√2-1)*(√2-1)
= √2-1/(2-√2-√2+1)
= √2-1/(-2√2+3)
For√2-i
the real part is is √2 and the imaginary part is -i
The multiplicative inverse is √2-1 = 1/(√2+1)
Rationalising the denominator we have
= 1/√2+1 * √2+1/√2+1
= √2+1/(√2+1)*(√2+1)
= √2+1/(2+√2+√2+1)
= √2+1/(2√2+3)
