Question

-2v3 + v75

How do I solve this and what would be the answer

Answers are either
3 √3
25 √3
-25 √3
-3 √3

Answer 1

a)
`3√(3)`

Explanation:

Step(i):-

Given - 2 √3 + √75

we know that 25 × 3 = 75

- 2 √3 + √75

= -2 √3 +
`√(25 X 3)`

By using

`√(ab) = √(a) √(b)`

=
`-2√(3) + √(25) X √(3)`

=
`-2√(3) + 5 √(3)`

=
`(-2 + 5 ) √(3)`

=
`3√(3)`
