Question

Simplify 1)  root 45 - 3 root 20 +4 Root 5 plzz write the sum

Answer 1

To simplify the given expression of root 45 - 3 root 20 + 4 root 5, combine the like terms to get root 5.

Step-by-step explanation:

To simplify the given expression:

Root 45 = 3 * root 5

-3 * Root 20 = -3 * 2 * root 5 = -6 * root 5

4 * Root 5 = 4 * root 5

Now, we can combine similar terms to get:

(3 - 6 + 4) * root 5 = 1 * root 5 = root 5

Answer 2

= root 45 - 3 root 20 + 4 root 5
= root 9 * root 5 - 3 * root 4 * root 5 + 4 root 5
=3 root 5 - 3 * 2 * root 5 + 4 root 5
= root 5 ( 3 - 6 + 4 )
= root 5 *1
= root 5
