Multiply or divide as indicated simplify your answer if possible

Step-by-step explanation:

We are given the following expression and we are to determine whether it is to be multiplied or divided and perform that operation on it accordingly:

The given expression indicates that the two terms are to be divided and we know that when two terms with same bases are divided, their exponents are subtracted.

Therefore, the simplified answer is .

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

1/4 because there is 4 grades.
