Question

Simplify.

-√m^4 n^7

Answer 1

Is your question \(-\sqrt{m^4n^7}\) ?

Answer 2

yes =))

Answer 3

So this would be \(-1\cdot \sqrt{m^4} \cdot \sqrt{n^7}\)

For every pair of 2 numbers inside the square root, 1 number comes out.

Answer 4

You can also rewrite the function as so: \(-(m^4n^6)^{1/2}\) and then multiply the half to both variables.

Answer 5

\[\large -(m^4)^{1/2} \cdot (n^7)^{1/2}\]

Answer 6

Second post has a typo, that should say ^7, not ^6*

Answer 7

So here you would get \[\large -(m^{4 \cdot 1/2}) \cdot n^{7 \cdot 1/2}\]

Answer 8

Now what is \[4\cdot \frac{1}{2} =~?\]\[7 \cdot \frac{1}{2} =~?\]

Answer 9

2
3.5

Answer 10

Yes, So you would have \[-m^2n^{7/2} \implies -m^2\sqrt{n^7}\]

Answer 11

so is tht the answer??

Answer 12

Yes.
