# Solve for c 16^2+30^2=c^2 162+302=c2
Rewrite the equation as c2=162+302.
c2=162+302
Take the square root of both sides of the equation to eliminate the exponent on the left side.
c=±162+302
The complete solution is the result of both the positive and negative portions of the solution.
Simplify the right side of the equation.
Raise 16 to the power of 2.
c=±256+302
Raise 30 to the power of 2.
c=±256+900
Add 256 and 900.
c=±1156
Rewrite 1156 as 342.
c=±342
Pull terms out from under the radical, assuming positive real numbers.
c=±34
c=±34
The complete solution is the result of both the positive and negative portions of the solution.
First, use the positive value of the ± to find the first solution.
c=34
Next, use the negative value of the ± to find the second solution.
c=-34
The complete solution is the result of both the positive and negative portions of the solution.
c=34,-34
c=34,-34
c=34,-34
Solve for c 16^2+30^2=c^2
