The answer is 4√6 4√x
Sorry if that looks confusing but it means small 4, big 6 and then small 4
Answer:
Step-by-step explanation:
sqrt(28): sqrt(4*7)
sqrt(4) = 2;
sqrt28)=2*sqrt(7)
sqrt(343): sqrt(7 * 7 * 7) = 7 * sqrt(7)
Note: the rule is if you have 3 equal primes under the root sign, you leave one, you throw one away, and you put one outside the root sign.
2 sqrt(63) = 2 sqrt(3*3*7) The above rule gets modified to throw 1 three away and take the other one outside the root sign.
2sqrt(63) = 2*3 sqrt(7)
Numerator: 2*sqrt(7) + 7sqrt(7) = 9sqrt(7)
9sqrt(7)
======
6 sqrt(7)
3/2
Note without brackets I cannot be certain that I have interpreted this correctly. The division only apply to sqrt(343) / 2 sqrt(63). If this is so please leave a note.
If it is (6^-4)^6 it should be 1/6^24. The picture was a bit blurry.

From the problem statement Melanie has 10 packets of 20 biscuits
60 biscuits
Solution
Let us find 3/10 of 10 packets
= 3 packets
In one packet there are 20 biscuits,
Hence in 3 packets there will be
20*3 = 60 biscuits
From the solution above Melanie served 60 biscuits in the plate
