Question 217939: ALRIGHT. SO THE PROBLEM IS WRITTEN AS FOLLOWS: +3%2Asqrt%28-75%29%2B5%2Asqrt%28-48%29+ PERFORM AND GIVE THE ANSWER IN STANDARD FORM. IM NOT SURE WHERE TO GO ON THIS ONE. WE CANT USE CALCULATORS ON OUR TESTS AND IM NOT SURE HOW TO DO THESE WHEN I DONT HAVE PERFECT SQUARES. IVE TRIED BREAKING THE SQUARES DOWN TO +5%2Asqrt%283%29+ AND +4%2Asqrt%283%29+ AND I KNOW THEY ARE BOTH IMAGINARY NUMBERS, BUT THATS AS FAR AS I CAN GET. CAN SOMEONE WALK ME THROUGH THE SOLUTION?

3sqrt(-75) + 5sqrt(-48)
.
3{sqrt(-1)*sqrt(3) *sqrt(25)} +5{sqrt(-1)*sqrt(16)*sqrt(3)}
.
{3*sqrt25}{sqrt(-1)*sqrt(3)} +{5*sqrt16}{sqrt(-1)*sqrt(3)}
.
{3*5}{ i*sqrt3} + {5*4} {i*sqrt3}
.
15 {i*sqrt3} + 20{i*sqrt3}
.
35 (i*sqrt3)
.
35 i sqrt 3,,,,,answer
