Simplify the expression 2 square root 20 minus 3 square root 7 minus 2 square root 5 plus 4 square root 63

2√5 + 9√7

Step-by-step explanation:

The given expression is

2√20 - 3√7 - 2√5 + 4√63

√20 = √4√5 = 2√5

√63 = √9√7= 3 √7

Now replace the above value with the given expression

2*2√5 - 3√7 -2√5+4*3√7

= 4√5 - 3√7-2√5+12√7

= 4√5 -2√5 - 3√7 +12√7

Simplifying the like terms, we get

= 2√5 + 9√7
