<u>ANSWER:</u>
The solution set for the inequality 7x < 7(x - 2) is null set 
<u>SOLUTION:</u>
Given, inequality expression is 7x < 7 × (x – 2)
We have to give the solution set for above inequality expression in the interval notation form.
Now, let us solve the inequality expression for x.
Then, 7x < 7 × (x – 2)
7x < 7 × x – 2 × 7
7x < 7x – 14
7x – (7x – 14) < 0
7x – 7x + 14 < 0
0 + 14 < 0
14 < 0
Which is false, so there exists no solution for x which can satisfy the given equation.
So, the interval solution for given inequality will be null set
Hence, the solution set is
<h2>A can complete the work in 7*6 hrs = 42 hrs.
</h2><h2>
</h2><h2>A can complete in 1 hr = 1/42 part.
</h2><h2>
</h2><h2>B can complete the work in 7*8 hr = 56 hrs.
</h2><h2>
</h2><h2>A&B together do in 1 hr = 1/42 + 1/56 = 7/168 = 1/24 part. So they will do in 8 hrs = 8*1/24 = 1/3 part.
</h2><h2>
</h2><h2>Hence they need 1÷1/3 = 3 days to complete the work.</h2>
The simplified form of the expression; (3/4)-¹ as given in the task content is; 4/3.
<h3>What is the simplified form of the expression as given in the task content?</h3>
It follows from the task content that the expression in discuss can be simplified as follows by the laws of indices;
(3/4)-¹
Hence, due to negative exponent, the result is;
= 1 ÷ (3/4)¹
= 1 × (4/3)
= 4/3.
