Answer:
+ 5.90
Because -5.90 in rational value is positive 5.90
Z^4 / z^-3 = z^7 - when you divide numbers written in exponential form, you keep the base and subtract the exponents. z^4 divided by z^-3 = z^ (4- (-3)) = z^7.
I got no solution as my answer. :/
-4x-12=16-4x
Add 12 on both sides of the equal sign.
-4x=28-4x
Add 4x on both sides of the equal sign.
0=28
2/5 + 3/8 = 16/40 + 15/40 = 31/40
= 1 to nearest 1
