Step-by-step explanation:
We apply the log rule that states that if there is a number multiplied by a log, the number becomes exponent of the argument of the log:
3 = log(8) + log(x^3)
Now we have sum of logs. Another property tells us that 2 logs with the same base a, that are added together, are equal to the log in base a of the product of the arguments:
3 = log(8x^3)
Now for definition of log:
10 ^ 3 = x^3
Therefore:
x = 10
Y = -14 i believe this is the correct answer
Answer:
x = 13
Step-by-step explanation:
call the missing number x
8 - x = - 5 Subtract 8 from both sides
8-8 - x = -5-8 Combine
-x = - 13 Multiply by -1
x = 13
<h3>
The smallest number that satisfies the inequality 3x -1>2 is 2</h3>
Step-by-step explanation:
3x -1>2
⇔3x > 2+1
⇔3x > 3
⇔x>1
Therefore 2 is the first number that is grater than 1.
So,
The smallest number that satisfies the inequality 3x -1>2 is 2
Answer:
