Exercise 10.2 | Q 2.1

If log 2 = 0.3010 and log 3 = 0.4771 ; find the value of : log 1.2

If log₅ x = y, find 5^{2y+ 3} in terms of x.

Prove that:

log₁₀ 125 = 3(1 - log₁₀2).

Write the logarithmic equation for:

E = `(1)/(2)"m v"^2`

Write the logarithmic equation for:

V = `(4)/(3)pi"r"^3`

Simplify the following:

`3"log" (32)/(27) + 5 "log"(125)/(24) - 3"log" (625)/(243) + "log" (2)/(75)`

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 720

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

Simplify: log b ÷ log b²
