If z = a-bi, the complex conjugate of z is a + bi.
So the imaginary part is "b"
"b" is opposite of -b, so correct answer is c)

The exponent would b 15
U just gotta solve it than u get 3375 than look for the square root of that and it’s 15over15
Ayy, so your question is kinda weirdly worded. But I think your asking what is 24 multiplied by 4 tons and 2 pounds.
Well, 2 pounds is equal to 0.00090718 tons.
There is a converter here: https://www.bing.com/search?q=pounds+to+tons&qs=AS&pq=pounds+to+tons&sc=8-14&sp=1&cvid=7BC591B75A8B4......
But now we have 0.00090718 tons as well as 4 tons. Add those together and you get 4.00090718. Now, multiply this by 24. You get: 96.02177232.
