Answer:
1)-1
2)-3
3)1
4)-3
5)2
Step-by-step explanation:
1) 2 to the power(x2+2x)=2 to the power negative one
2) so x2+2x+1=0
3) (x+1)2=0
4) x=-1
1) 2 to the x-3= 2 cubed times x+1
2) x-3=3x+3
3) 2x=-6,x=-3
1) 5/2-k/2=3-k
2) 5-k=6-2k
3) k=1
1) 3 to the x+3= 3 cubed times 2x+6
2) x+3=6x+18
3) 5x=-15,x=-3
1) 5 to the x-2= 5 to the 0
2) so x-2=0
3) x=2
