Align Left move picture left Align Center move picture to the center Align Right move picture right Also in the text area i have to put the size of the picture and be able to change it by typing a new size and pressing the button Resize. PLEASE HELP (i am a beginner.... )

but is this steps right? 36.65=20n => =>n=log2036.65

i have this : 15,76=0.43*(20)n i have to calculate n... 15.76/0.43=20n 36.65=20n n=log2036.65 is this right???

Simplify this Boolean expression : F(a,b,c)=((c+a)' *(c⊕b)')' My answer is:F= ((c'*a')*(cd+c'd'))'=(c'*a')'+(cd+c'd')'=c+a+(c'd'*cd)=c+a Is that right? If not explain?

Simplify this Boolean expression please: F(a,b,c)=((c+a)' *(c⊕b)')' ⊕=XOR
