Answer 1

3 x 3 x 3 is equal to 27 3cube

Answer 2

Answer:

3 or 6

Step-by-step explanation:

dear friend,

f(f(f(k))=27 is given

=f(f(k+3))=27 bcoz given that k is odd

=f(k+3/2)=27 bcoz odd+3=even everytime

but now we get two cases since anything/2=odd or even

so we would get either of (k+6 or k+3/4)=27

i.e.k=21 or k=105

therefore sum of the digits is either 3 or 6......hope it helps...pls mark my ans the brainliest as u promised..tq..
