Eliminate the radical by squaring both sides of the equation.

Solve for c.

Substitute the value of c into the original equation.

Given: #sqrt(c+10)=4#

Square both sides:

#c+10 = 16#

Subtract 10 from both sides:

#c = 6#

Substitute 6 into the original equation:

#sqrt(6+10)=4#

#sqrt(16) = 4#

#4 = 4#

This checks.
