Given log6=0.778,find log36.

We know that

1 ) log a^n = n log a

Now ,

log 6 = 0.7782 ( 1 )

log 36 = log 6²

= 2 log 6

= 2 × 0.7782

= 1.5564

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
