Question

Multiply and simplify if possible.
√7x (√x-7√7)

Answer 1

thank you so much, and I really appreciate the way you are explaining the answer to me.

Answer 2

\[\sqrt{7x} =\sqrt{x-7\sqrt{7}}\]THIS? OR what?

Answer 3

Can you just draw it or use equation editor, because I don;t get the question.

Answer 4

you got it correct, but there is no equal sign, and the ending is in para. strange isn't it. let me post it again

Answer 5

\[\sqrt{7x}\sqrt{x-7\sqrt{7}}~~~like~~this?\]

Answer 6

yes, that's it

Answer 7

\[\sqrt{7x} \times \sqrt{x-7\sqrt{7}}\]I don;t think there is a way to simplify this.

Answer 8

Actually, my bad....

Answer 9

\[\sqrt{7x} \times \sqrt{x-7\sqrt{7}}~~~~->~~~~~\sqrt{\color{red} {{7x \times (x-7\sqrt{7})}}}\]

Answer 10

ok, so it cannot be simplified, hmmm let me write this one.

Answer 11

\[\sqrt{7x^2-49x \sqrt{7}}\]I think that's the most I can simplify, that's it, and that's the answer.

Answer 12

It could be, see my replies?

Answer 13

\[I~~USED:~~~\sqrt{a} \times \sqrt{b}=\sqrt{a \times b}\]
