Multiply √144 * √-1 ? | i^2 =-1 and i=-1 √144=12 √144*√-1 12 * i= 12i |
Add: (6+5i)+(4-4i) | The terms 6 and four are alike and the terms 5i and -4i are also like terms =10+i |
Multiply: -10i * -5i ? | Multiply as you would normally then remember that i^2 = -1 and simplify. -10i * -5i 50i^2= -50 |
√144 *√-1 Divide: √-72/-9 ? | √144 *√-1 √-72/√-9 i√72/i√9 divide the i ‘s √72/√9 √72/9 √8=√4*√2= 2√2 |
