Could someone show me how to get the work for:
3/4 (sqrt)16/25 ?
The answer says 3/5i.
Could anybody tell me how to get there and work with complex fractions and simplify them? Thanks!
3/4 SQRT(16/25)
3/4 SQRT( 16/25*1)
3/4 *4/5 *SQRT( 1)
but the sqrt of 1 is defined as i, so
3/4 *4/5 *SQRT( 1)=
3i/5
i did this the first time, but was like... no that's not right. i feel quite dumb.
ahhh.. thank you so much!
