Answer:

it can't be done... unless you add the i

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

plz say thanks
