Answer:
it can't be done... unless you add the i
Step-by-step explanation:
so 10 x10= 100
and -10 x -10 = 100
so -10 x 10
would be the answer only you have to find two indentical numbers
the answer is 0 + 10i
why?
the square root of -1 is i
if you x the two roots together( of -1 and 100) it would leave you with 10i which is exactly what we wanted!
10 i =10 x -10
but the problem is 10i is one number... so we write it as this...
square root of -100 = 10i x 0
