Answer:
1. 
2. 7
3. 18
Step-by-step explanation:
Question 1:
Given:
The expression to simplify is
.
We use the property of exponent 
Therefore, 
Question 2:
Given:
The expression to simplify is
.
We add the fractions first inside the parenthesis.
So, 
Now, 
Question 3:
The first five prime numbers are 1, 2, 3, 5, and 7.
Therefore, the sum of these five numbers is given as:


Euclid's division lemma : Let a and b are two positive integers. There exist unique integers q and r such that
a = bq + r, 0
r < b
Or We can write it as,
Dividend = Divisor × Quotient + Remainder
<u>Work</u><u> </u><u>out</u><u>:</u>
Given integers are 240 and 228. Clearly 240 > 228. Applying Euclid's division lemma to 240 and 228,
⇛ 240 = 228 × 1 + 12
Since, the remainder 12 ≠ 0. So, we apply the division dilemma to the division 228 and remainder 12,
⇛ 228 = 12 × 19 + 0
The remainder at this stage is 0. So, the divider at this stage or the remainder at the previous age i.e 12

Answer:
25/35
Step-by-step explanation:
5 times 7 equals 35 and that means that this is the denominator because that is our total amount.
5 times 5 equals 25 and that makes it the numerator because that is what is being taken out of 5 jars
Hopefully this helps you :)
First of all, don't let "b" confuse you. Know that b = 5/6k = -10, so all you really have to solve for this problem is
.
Before anything else, you have to isolate k. Do this my multiplying both sides by the reciprocal of 5/6.

The 6/5 and 5/6 cancel each other out, so we are left with 
--> 
---> 
So k = -12.
Hope this helped. Good luck.
