Question

Simplify (-10-sqrt125)/25

Answer 1

HI!!

Answer 2

Hello can you help please!

Answer 3

\[125=25\times 3\] so \[\sqrt{125}=\sqrt{25\times 3}=\sqrt{25}\sqrt3=5\sqrt3\]

Answer 4

Don't you mean 25 x 5?

Answer 5

so you have \[\frac{-10-5\sqrt5}{5}\] as a start
divide each by 5

Answer 6

oops yeah that is what i meant sorry
last box is correct though

Answer 7

Also what happened to the 25? How did it turn into a 5

Answer 8

\[\frac{-10-5\sqrt5}{5}\] each gets divided by \(5\)

Answer 9

it turned in to a five because you were taking the square root of 25
\[\large \sqrt{125}=\sqrt{25\times 5}=\color{red}{\sqrt{25}}\sqrt5=\color{red}5\sqrt5\]

Answer 10

If each was divided by 5 then wouldn't it be
(-2 - sqrt5)/5

Answer 11

no

Answer 12

when you divide by 5, there is no more denominator

Answer 13

\[-\frac{10}{5}=-2\\
-\frac{5\sqrt5}{5}=-\sqrt5\]

Answer 14

final answer \[-2-\sqrt5\] the \(5\) in the denominator is gone

Answer 15

can u help me misty please

Answer 16

Okay I see

Answer 17

oh wait hold on i made a mistake sorry

Answer 18

the denominator is 25, not 5, you were right to begin with

Answer 19

your answer was correct, only a five cancels so you were correct \[\frac{-2-\sqrt5}{5}\]

Answer 20

yes , this one is correct :) @misty1212
