#6 ... when you find the sqrt of a number, the radical disappears. And the - sign makes this an imaginary number, the neg comes out and becomes an 'i'

#12 Again the radical disappears

#24 CORRECT!!!

#2 Continue on ...

#24 Continue on ...

6. SQRT-121=11i (i=SQRT-1)
12. SQRT4/25=2/5
24. 3SQRT(8/27)=3*2/3SQRT92/3)=6/3SQRT(2/3)=2SQRT(2/3)
2. SQRT(50)=SQRT(25*2)=5SQRT2
24. SQRT(72X^3)=SQRT(6^2*2)(X^2*X)=6XSQRT(2X)
