yes, you are right ___ it appears that your technique is fine
D is similar to E ___ [sqrt(1)]/[sqrt(625)] ___ 1 / 25
A is -1 times 169 ___ the sqrt of -1 is "i" and the sqrt of 169 is 13 ___ so 13i
B is also similar to E ___ [sqrt(121)]/ [sqrt(2)] ___ 11 / √2
___ by convention, sqrts are not left in the denominator ___ so multiply the fraction by one (√2 / √2)
___ 11√2 / 2
C is negative so "i" is used again
___ it may be easier to convert the decimal to a fraction
___ -64 / 100 ___ 8i / 10
___ converting back ___ .8i
hope this helps
