d) sqrt (7)
c im just making show that they are correct sorry for posting up so many
yup
To simplify √(28), we can look for perfect square factors of 28.
Step 1: Prime factorize 28 -> 2 * 2 * 7
Step 2: Group the numbers in pairs and take the square root of each pair:
√(2 * 2 * 7) = √(4) * √(7)
Step 3: Simplify the square root of the perfect square:
√(4) = 2
Final answer: 2√(7)
So, the correct answer is option c) 2√(7).
