Answer:
-3root 3=-5.19615224225
Step-by-step explanation:
root 75-4root 12
root 75
simplify root
=root 25×3=root 5square×3
=5root 3
5root 3-4root 12
4root 12
simplify root
=4root 4×3=4root 2square×3=2×4root 3
=8root 3
5root 3-8root 3
5root 3-8root 3
subtract these number
=-3root3
therefore-3root 3=5.19615242225
