Given that a = 0.1039
To find the value of
√(4a² - 4a + 1)
Here instead of substituting the value, we will find the square root of the equation.
Here if we see,
4a² = (2a)²
1 = (1)²
and -4a = -2(2a)(1)
=> 4a² - 4a + 1 = (2a - 1)²
So √(4a² - 4a + 1)
= √(2a - 1)²
= 2a - 1
So now substitute the value of a
=> 2(0.1039) - 1
=> 0.2078 - 1
=> (-0.7922)
Hope it helps dear friend ☺️✌️

no, if you dont believe me i will send the photo
Then how can the answer be option c : thinking face:
Can you find any mistake in my answer? If yes then do tell me
i also dont know . thats why i asked it
maybe options are wrong
hehehe, i havent see your answer
because third option is not possible. If you will add 1 and 0.1039 the outcome will be positive but option has given negative
yaah, may be
ok , dont take it seriously. it is only for 1 marks . i believe that your answer us 100% correct
if you say so
