If Log 27 = 1.431, Find the Value of : Log 300

If log 27 = 1.431, find the value of : log 300

Sum

log 27 = 1.431
⇒ log 3 x 3 x 3 = 1.431
⇒ log 3³ = 1.431
⇒ 3log3 = 1.431
⇒ log 3 = `1.431/3`
⇒ log 3 = 0.477 ...(1)

log 300
= log( 3 x 100 )
= log 3 + log 100
= log 3 + 2 ...[ ∵ log₁₀100 = 2 ]
= 0.477 + 2
= 2.477

Prove that : (log a)² - (log b)² = log `(( a )/( b ))` . Log (ab)

If 2 log y - log x - 3 = 0, express x in terms of y.

Given: log₃ m = x and log₃ n = y.
If 2 log₃ A = 5x - 3y; find A in terms of m and n.

Given `log_x 25 - log_x 5 = 2 - log_x (1/125)` ; find x.

Express the following in terms of log 5 and/or log 2: log125

Write the logarithmic equation for:

n = `sqrt(("M"."g")/("m".l)`

Simplify the following:

`12"log" (3)/(2) + 7 "log" (125)/(27) - 5 "log" (25)/(36) - 7 "log" 25 + "log" (16)/(3)`

If log 16 = a, log 9 = b and log 5 = c, evaluate the following in terms of a, b, c: log 12

If x² + y² = 7xy, prove that `"log"((x - y)/3) = (1)/(2)` (log x + log y)
