a) x=4
b) x=40
c) x=1,000
d) x=10,000

Answer 1

Answer:

d) x=10,000

Step-by-step explanation:

convert log(base10)x=4 to 10^4=x   x=10,000

Answer 2

Answer:

Option d - $x=10000$  

Step-by-step explanation:

Given : Expression $\log x=4$  

To find : Solve the expression ?

Solution :

Step 1 - We re-write the expression,

$\log_{10} x=4$  

Step 2 - Apply logarithmic property, $\log_b x=a\implies x=b^a$

$x=10^4$  

Step 3 - Solve

$x=10000$  

Therefore, Option d is correct.
