How do you approximate

lo g_{7} 16

lo g_{7} 2 = 0.3562

lo g_{7} 3 = 0.5646

https://socratic.org/questions/how-do-you-approximate-log-7-16-given-log-7-2-0-3562-and-log-7-3-0-5646

Noah G Nov 14, 2016 We have that

16 = 2^{4}

2 \times 2 \times 2 \times 2

. Writing in logarithms, we have:

lo g_{7} (16) = lo g_{7} (2 \times 2 \times 2 \times 2)

How do you simplify

lo g_{3} 27 + 6 lo g_{3} 9

https://socratic.org/questions/how-do-you-simplify-log-3-27-6log-3-9

lo g_{3} 27 + 6 lo g_{3} 9 = (15)

Explanation: Always remember when dealing with log functions

(XXX) lo g_{b} a = c \Leftrightarrow b^{c} = a

How do you simplify

lo g_{3} 3 + lo g_{2} 64

https://socratic.org/questions/how-do-you-simplify-log-3-3-log-2-64

lo g_{3} (3) + lo g_{2} (64) = 7

Explanation: We use identities

lo g_{a} a = 1

lo g_{a} (a^{m}) = m

How do you find the exact value of

lo g_{5} 75 - lo g_{5} 3

https://socratic.org/questions/how-do-you-find-the-exact-value-of-log-5-75-log-5-3

lo g_{5} 75 - lo g_{5} 3 = 2

Explanation: Remember that

lo g_{a} b - lo g_{a} c = lo g_{a} (\frac{b}{c})

∴ lo g_{5} 75 - lo g_{5} 3 = lo g_{5} (\frac{7 5}{3}) = lo g_{5} 25

How do you subtract

lo g_{2} 12 - lo g_{2} 3

https://socratic.org/questions/how-do-you-subtract-log-2-12-log-2-3

lo g_{2} 12 - lo g_{2} 3 = 2

lo g_{2} 12 - lo g_{2} 3 = lo g_{2} (\frac{1 2}{3}) = lo g_{2} 4 = 2
