Question

3 – 5 log₁₀ 2 is equal to ______.

विकल्प

• `log  225/4`

• `log  125/4`

• `log  75/4`

• `log  25/4`

Answer 1

3 – 5 log₁₀ 2 is equal to `underlinebb(log  125/4)`.

Explanation:

3 = log 10³ 

= log 1000

And 5 log 2

= log 2⁵ 

= log 32

So 3 – 5 log 2

= log 1000 – log 32

= `log (1000/32)` 

= `log (125/4)`
