\[-\sqrt{8}-4\sqrt{7}+2\sqrt{72}-2\sqrt{7}\]

all you can do is simplify

combine like radicals

can u work it out and show me please

you can further simplify -\[\sqrt{8}\]

yes

thank you

\[-\sqrt{8}\] is really -\[\sqrt{4x2}\]

the 4 comes out as a 2 because the sq root of 4 is 2. put it out front with the negative sign

-2\[-\sqrt{2}\]

crap

-2√2

the -4√7 and -2√7 become -6√7

2√72 can be 2√(9)(8)

9 pops out as 3, multiply it with the 2 to get 6√8, this further simplifies too

6√(4)(2)

4 pops out as 2, times it by 6 for 12√2

combine that with our other √2 we first simplified

10√2 - 6√7 all done

thats the answer

yes, you cant simplify any further
