Alright, we're in the home stretch here :) All you need to remember is that i² = -1. Otherwise, it is the same as FOIL
(3-2i)(1+7i)
3-2i+21i-14i² ← Replace the i² with -1, then simplify like numbers
3+19i+14
17+19i or C
I think its d or a pick one
Answer:
2.32 x 10 put the minus sign at the top with a 11.
Step-by-step explanation:the answer is: move the decimal so there is one non-zero digit to the left of the decimal point. the number of decimal places you move will be the exponent on the 10. the sign of the exponent will depend on the direction you are moving the decimal. hope this helps! ;)
