Work: Calculate the value of equation -3^2-125*(-2/5)^2-8/(13)^2 .
Question type: Mathematical calculation
Solution:
-3^2-125*(-2/5)^2-8/(13)^2
=-3^2-125*(-0.4)^2-8/(13)^2
=-3^2-125*(-0.4)^2-8/13^2
=9-125*(-0.4)^2-8/13^2
=9-125*0.16-8/13^2
=9-125*0.16-8/169
=9-20-8/169
=9-20-0.047337
=-11-0.047337
=-11.047337
Answer:-3^2-125*(-2/5)^2-8/(13)^2=-11.047337
