Question

2 log 5 + +1/2 log 9 - log3 = logx find x .. ​

Answer 1

Answer:

25

Step-by-step explanation:

2 log 5 + 1/2 log 9 - log 3 = log x

Using Power rule m.log a = log a^m

=> log 5² + log 9^( ½ ) - log 3 = log x

=> log 25 + log √9 - log 3 = log x

=> log 25 + log 3 - log 3 = log x

=> log 25 = log x

=> 25 = x

Therefore the value of x is 25.

Answer 2

Answer:

x = 25

Step-by-step explanation:

2 log 5 + $\cfrac {1}{2}$ log 9 - log 3 = log x

⇒ $\log 5^2 + \log 9^{1/2} - \log 3 = \log x$

⇒ $\log 25 + \log 3 - \log 3 = \log x$

⇒ $\log 25 = \log x$

⇒ x = 25
