Question

Simplify the following expressions.

Answer 1

\[(-2ab^3)(5a^-4b^4)\]

Answer 2

The a is a^-4 btw

Answer 3

@dude

Answer 4

\((−2ab^3)(5a^{−4}b^4)\)
Do you have an idea on what to do?

Answer 5

Kinda....

Answer 6

Not really though.

Answer 7

Would it be like \[-2*a*b^3*5*a^-4*b^4\]

Answer 8

you need to know that

a^(-1) = 1/a

yes ?

Answer 9

and multiply the same terms

−2∗a∗b3∗5∗a−4∗b4 = (-2*5)×(a/(a^4)) × (b^3 *b^4) = ?

hope this will help you

Answer 10

@justasoftie

Answer 11

Oh I don't know then. Sorry I couldn't help

Answer 12

@jhonyy9 so -10a^-3b^12?

Answer 14

Still working on the problem up top?

Answer 15

Yes sir, and I still have 15 questions left and this is a study guide for my test tomorrow... I’m so screwed..

Answer 16

\[(-2ab ^{3})(5a ^{-4}b^{4}) \]
\[(-2ab ^{3})(5\frac{ 1 }{ a ^{4} } b^{4}) \]
\[(-2 \times 5)( a \times \frac{ 1 }{ a ^{3}})(b ^{3} \times b ^{4})\]
\[(-10)(\frac{ a }{ a^{4} })(b ^{3 + 4})\]
\[\frac{ -10 b ^{7} }{ a ^{3}}\]

Answer 17

Do you understand the steps?

Answer 18

\[\frac{ a }{ a^4 } = \frac{ 1 }{ a^3 }\]

Answer 19

I think so, can you help me work out the second one?

Answer 20

Sure
