# Math Help - negative radical simplify

i feel stupid asking this im probably overthinking it..but i cant get the answer wrong so ill ask anyway..

$\sqrt{-4}*\sqrt{-49}$

if i go $\sqrt{-49*-4}=\sqrt{196}=14$

however i can also go(i think) $2i*7i=14i^2=14*-1=-14$

so is the answer $\pm 14$? or is it one or the other....

2. Order of operations tells us that exponents comes before multiplication.
