Answer: 777600
Step-by-step explanation:
you times 12 by 4 then you times 3000 by 5.4 and add the two answers
An imaginary number " i " is the squared root of -1, so whenever you square i it's like squaring a squared root. The squared root would cancel and you would be left with just the number under it, that is, the -1.
i ^ 2 = -1
x^5 is your answer because you add exponents when they are not in separate paretheses.
In your equation: a+(-4)=-13
you then add four to each side,
so a= negative 13 plus 4
so a= -9
The answer should be -3/28
