1/r-1/(r(1+r)^3)=2.673
We move all terms to the left:
1/r-1/(r(1+r)^3)-(2.673)=0
Domain of the equation: r!=0
r∈R
Domain of the equation: (r(1+r)^3)!=0We add all the numbers together, and all the variables
r∈R
1/r-1/(r(r+1)^3)-(2.673)=0
We add all the numbers together, and all the variables
1/r-1/(r(r+1)^3)-2.673=0
We calculate fractions
(1*(r(r+1)^3))/(r*(r(r+1)^3))+(-r)/(r*(r(r+1)^3))-2.673=0
We calculate terms in parentheses: +(1*(r(r+1)^3))/(r*(r(r+1)^3)), so:
1*(r(r+1)^3))/(r*(r(r+1)^3)
We multiply all the terms by the denominator
1*(r(r+1)^3))
Back to the equation:
+(1*(r(r+1)^3)))
We calculate terms in parentheses: +(-r)/(r*(r(r+1)^3)), so:We add all the numbers together, and all the variables
-r)/(r*(r(r+1)^3)
We multiply all the terms by the denominator
-r)
Back to the equation:
+(-r))
(1*(r(r+1)^3)))+(-1r))-2.673=0
