Question

Which expression is equivalent to the given expression?

8(3/4a)−8

1. 3/4a
2. 6a
3. 8(3/4a - 1)
4. 3/4a -1

Answer 1

the answer is 3 cause we can factor 8 from the whole equasion .
that means to take 8 out of every given data so
since we have 8 multiple 3/4a we can have an 8 and we also have -8 so we can divide it to 8 and take 8 out of it which leads us to 8(3/4a-1)

Answer 2

`8 \{((3)/(4a) ) - 1\}`

Explanation:

8 (3/4a) - 8

The above expression can be written as:

`8((3)/(4a)) -8(1)`

Since 8 is a common factor here which is multiple of 3/4a as well as 1 therefore taking 8 as a common factor from whole equation,

`8 \{((3)/(4a) ) - 1\}`

Therefore option (3) is the correct answer.
