You can put this solution on YOUR website! V63 - 2V28 + 5V7
make factors of values which are inside the root ,,,and we get
V3*3*7 - 2V2*2*7 + 5V7
Now u know that the for every two same numder inside the square root we get one of that num outside the squareroot,,,so we get ...
3V7 - 2*2V7 + 5V7
= 8V7 - 4V7
= 4V7
hope this will help you
