2√72 / √8 ± √2
If the denominator is √8 + √2,
2√72 / √8 + √2
= 2√(2*2*2*3*3) / √(2*2*2) + √2
= 2*2*3√2 / 2√2 + √2
= 12√2 / 3√2
= 4
What would make finding the answer a bit easier, is converting them into improper fractions. You would turn that first fraction to
and the second fraction to
. (You are dividing a negative by a negative, therefore, your answer would be a positive.
Let's follow the procedure of keeping, switching, and flipping. You keep the first improper fraction, switch the division sign to a multiplication sign, and flip the second fraction. That would make it :
×
.
You multiply the 9 and the 2, you get 18. You multiply the 3 and the 4, you get 12. That makes it
. This, converted to a mixed fraction, makes 1
., which is the same as 1
. Your answer is the
SECOND CHOICE.
