\[\pm i\frac{\sqrt{15}}5=\pm i\frac{\sqrt{3\cdot5}}5=\pm i\sqrt{\frac{3\cdot5}{25}}=\pm i\sqrt{\frac35}\]
oo but the i was over 5 to begin with
but the 5 can move around...
ok let me try to process this xD
\[\pm\frac i5\sqrt{15}=\pm i\frac{\sqrt{15}}5=\pm i\frac{\sqrt{3\cdot5}}5=\pm i\sqrt{\frac{3\cdot5}{25}}=\pm i\sqrt{\frac35}\]
remember that\[\frac{2i}3=i\frac23\]not\[\frac{2i}3=\frac i3\frac23\]
\[a\frac bc=b\frac ac=\frac{ab}c\]
:O it is???
ooo
what else could it be?
THANKSSS
\[\frac{ab}c=a\cdot\frac bc\neq\frac ac\cdot\frac bc\]
welcome :D
