Question

simplify 3 power -3.9power-3​

Answer 1

Answer:

=2.528

Step-by-step explanation:

so the question is (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

=2.528
