7 √3x + 2 √3x – 3 √3x?

This question contains the adding and subtracting the similar radical terms containing √3 with variable x.

The first step of the question is solving for 7 √3x + 2 √3x = 9 √3x

Now subtract 3 √3x from the earlier answer 9 √3x

This makes 9 √3x – 3 √3x = 6 √3x

Therefore simplifying the radicals gives 7 √3 x + 2 √3x – 3 √3x = 6 √3x

Hence solution = 6 √3x.

3√5x + 2√5x – √5x?

This question contains the adding and subtracting the similar radical terms containing √5 with variable x.

The first step of the question is solving for 3√5x + 2√5x = 5√5x

Now subtract √5x from the earlier answer 5√5x

This makes 5√5x – √5x = 4√5x

Therefore simplifying the radicals gives 3√5x + 2√5x – √5x = 4√5 x.

Hence solution = 4√5x.
