Answer 2

The required value of t is equal to 2

Step-by-step explanation:

We need to solve the following expression :

`\log_4(7t+2)=2`

Now, using the base rule :

`2=\log_4(4^2)\\\\\implies 2= \log_4(16)`

Now, using this value of 2

`\log_4(7t+2)=2\\\\\implies\log_4(7t+2)=\log_4(16)\\\\\implies 7t+2=16\\\\\implies 7t=16-2\\\\\implies 7t=14\\\\\implies t = 2`

Hence, The required value of t is equal to 2
