Logarithms (Please do what the question is asking)

 1) 2.059

               2) 3.220

Step-by-step explanation:

1) log₆ 40

= log₆(5 x 8)

= log₆5 + log₆8

= 0.898 + 1.161

= 2.059

2) log₆ 320

= log₆ (40 x 8)

= log₆40 + log₆8

= 2.059 + 1.161

= 3.220

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
