Question

Simpligy

Answer 1

-√48 +27

Answer 2

My answer was -√3

Answer 3

\[-\sqrt{48}+27\]
\[\sqrt{48}=\sqrt{3}\cdot \:4\]
\[=-\sqrt{3}\cdot \:4+27\]
\[-\sqrt{48}+27=-\sqrt{3}\cdot \:4+27\quad \left(\mathrm{Decimal:\quad }\:20.0718\right)\]

Answer 4

when simplifying radicals think like what number that's a perfect square is a factor of it

or does 48

go into

4
16
9

then pretend that the radical isn't there.

16* 3 = 48

\[-\sqrt{16}*\sqrt{3} = -\sqrt{48}\]

\[-4\sqrt{3} + 27 \]
