27/343*49/81*3/7

3963/194481

Answer 2

(7/3)to the power -3 into( 9/7)to thepower -2 into( to the power one 3/7)

now to remove minus we will do reciprocal of 7/3 so it will become = 3/7 to the power 3

same we will do with 9/7 so it will become= 7/9 to the power 2.

now next we will == (3/7) to d power 3 multiply by 3/7 to the power 1.

so powers will add on because base is same so answer is== (3/7) to the power 4

now 9/7 to the power -2 is left so we will hv to do reciprocal of this because the power is negative....so answer will come 9/7 to the power 2 positive...

now we r left with 9/7 and 3/7 so we will solve them

( 9/7) to the power 2 multiply by( 3/7) to the power 4

so by solving this we will get = 1/21

this iz the right answer....hope this was helpfull mark me as brainliest
