If log[2](7) = a and log[2](5) = b express in terms of a and b the formulas
i)
log[2](35)
log[2](7*5)
log[2](7) + log[2](5)
a + b
ii)
log [2](2.8)
log [2](7 * .4)
log [2](7 * 4/10)
log [2](7) + log [2](4/10)
log [2](7) + log [2](4) - log [2](10)
log [2](7) + log [2](2^2) - log [2](5*2)
log [2](7) + log [2](2^2) - (log [2](5)+log [2](2))
log [2](7) + log [2](2^2) - (log [2](5)+log [2](2^1))
log [2](7) + log [2](2^2) - (b+1)
log [2](7) + log [2](2^2) -b-1
a + 2 -b-1
a-b+1
