Question

Its not letting me write the equation here, click and I'll add details..

Answer 1

\[-\left( 10a ^{3}b \div25a ^{8}b\right)\]

Answer 2

\[\Large -(10a^3b \div 25a^8b)??\]

Answer 3

Oh, I forgot, the entire thing is squard

Answer 4

i cant read well sorry haha too small for me

Answer 5

squared*

Answer 6

You typed it right though

Answer 7

\[\LARGE -(10a^3b \div 25a^8b)^2?\]

Answer 8

Yes

Answer 9

well first step rewrite as fraction...usually easier

Answer 10

\[\LARGE -(\frac{10a^3b}{25a^8b})^2\]

Answer 11

Yeah, thats how it appeared on the paper I just wasn't sure how to write it out on here, haha

Answer 12

I still don't know how to solve it...can anyone help?

Answer 13

well first you solve what's inside the parenthesis...forget the square first... \[\large \frac{10a^3b}{25a^8b} = \frac{10}{25} \times \frac{a^3}{a^8} \times \frac {b}{b}\]

Answer 14

do you know how to simplify that now?

Answer 15

The \[\left(\begin{matrix}b \\ b\end{matrix}\right)\] gets canceled out...

Answer 16

uhh yeah it becomes 1...what abt the rest

Answer 17

then its 1/\[a{5}\]

Answer 18

Sorry I dunno how to write fractions on here

Answer 19

1 over a to the 5th

Answer 20

and the 10/25 becomes 2/5?

Answer 21

you got it! \[\Large \frac{10a^3b}{25a^8b} = \frac{2}{5a^5}\] now what do you think you do next?

Answer 22

Now square everything? So 2/10a^10..?

Answer 23

And simplify to 1/5a^10?

Answer 24

are you sure /:)

Answer 25

Not exactly...do you multiply or add the exponents

Answer 26

okay hint.... \[\Large (\frac{2}{5a^5})^2 = \frac{(2)^2}{(5)^2 \times (a^5)^2}\]

Answer 27

Ohh right, the numerator is 4. Oops

Answer 28

Over 10 x a^10?

Answer 29

25*

Answer 30

so it's \[\large \frac{4}{25a^{10}}?\]

Answer 31

I think so..

Answer 32

But negative, because there was a negative sign before the paranthesis

Answer 33

good!

Answer 34

that's the answer

Answer 35

Thank you! :)
