Rewrite the following without an exponent.

(9/8)^-1 = 8/9

Step-by-step explanation:

To re write without an exponent means we will eliminate it's power.

This fraction came with the power of -1.

And when the power of a fraction or a whole number comes with power of -1 what it simply means it's the inverse of the number.

So let's evaluate the above fraction.

(9/8)^-1 = 1/(9/8)

(9/8)^-1 = 1*(8/9)

(9/8)^-1 = 8/9

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
