Answer:
Answer = 2.528
Explanation:
(3/4)*-2/(4/5)*-3*(3/5)*-2
firstly convert the negative powers into positive:(4/3)*2/(5/4)*3*(5/3)*2
so it will be as:(16/9)/(64/125)*(25/9)
for making it easy make reciprocal of the second and change division into multiplication :(16/9*64/125)----16*64=1024 and 9*125=1125
divide both number now---->0.190
now multiply that with:0.190*25/9
Then gets you the answer.
