Question

The simplified form of √125 + √125 - √845 is​

Answer 1

Answer:

(-3√5)

Step-by-step explanation:

√125=√(25*5)=5√5

√845=√(169*5)=13√5

Now,√125 + √125 - √845 = 5√5+5√5 - 13√5

=10√5-13√5

= (-3√5)

Answer 2

Answer:

After simplifying the expression √125 + √125 - √845 , we get -3 √5.

Step-by-step explanation:

√125 + √125 - √845

We first will factorize each of them to solve the root:

125 = 5 × 5 × 5

845 = 5 × 13× 13

From this, we get that:

√125 = 5 √5

√845 = 13 √5

Now the expression is:

√125 + √125 - √845

Substituting the values:

= 5 √5 + 5 √5 - 13 √5

Simplifying the expression:

= 10 √5 - 13 √5

= -3 √5

Therefore, after simplifying the expression √125 + √125 - √845 , we get -3 √5.
