Step by action solution :
Step 1 :
Isolate the square root on the left hand next :Radical already isolated √(9/10)=x
Step 2 :
Eliminate the radical ~ above the left hand next :Raise both political parties to the 2nd power(√(9/10))2=(x)2After squaring (9/10)=x2
Step 3 :
Solve the quadratic equation :Rearranged equationx2(9/10)=0This equation has two real roots: x1=( 0+sqrt( 4))/ 2=0.9487 x2=( 0sqrt( 4))/ 2=0.9487
Step 4 :
Check that the very first solution is exactly :Original equation√(9/10)=xPlug in 0.9487 because that x√(9/10)=( 0.9487) Simplify√0.9=0.949Solution check !!Solution is: x= 0.9487
Step 5 :
Check that the second solution is exactly :Original equation√(9/10)=xPlug in 0.9487 for x√(9/10)=(0.9487) Simplify√0.9=0.949Solution walk not inspect 0.949≠0.949
One systems was uncovered :
x= 0.9487You are watching: Square root of 9/10
