Number 5 i am so lost is it possible to do without a calculator?

It would not be possible from where i see it,  if it were 2 the equation would be 2^(2+3)=3^(2*2-1) or 2^5=3^3 or 32≠27

There is no image given.

128/3reason being 5 and 1/3 = 16/316/3 • 2/3 = 32/31 and 1/3 = 4/3 32/3 • 4/3 this will equal 128/3
