# -5x the square root of 7-14 x the square root of 7

Neethu | Certified Educator

We have to evaluate,

-5\sqrt{7}-14\sqrt{7}=\sqrt{7}(-5-14)      (Taking \sqrt{7} common)

=\mathbf{-19\sqrt{7}}

Question:-

-5x the square root of 7-14 x the square root of 7

-5sqrt(7)-14sqrt(7)=?

SOLUTION:-

-5sqrt(7)-14sqrt(7)

Since the radicals are same therefore we will be Taking sqrt7  common and then combine them:-

=sqrt7(-5-14)

=sqrt7(-19)



After simplifying and taking sqrt(7) common, and further simplification, we get the following answer that cannot be further simplified.

-19sqrt7

Therefore this is the final answer.

Hence Solved!

The simplification of  involves operation of radicals(i.e an expression that has a squareroot, cube root etc.).

Since the radical is the same in each term we can combine the terms.

So,

Therefore, the required annswer is  .

The simplification of -5*sqrt7-14*sqrt7 involves operation of radicals(i.e an expression that has a squareroot, cube root etc.).

Since the radical is the same in each term we can combine the terms.

So, -5*sqrt7-14*sqrt7

=sqrt7(-5-14)

=-19sqrt7

Therefore, the required annswer is -19sqrt7 .
