Answer:
log x²
Step-by-step explanation:
Using the rules of logarithms
log x + log y ⇔ log xy
log ⇔ n log x
Given
2logx + 4logy
= logx² + log
= log x²
Answer:
the gross monthly income for 4 weeks is $1,887.20
Step-by-step explanation:
The computation of the gross monthly income for 4 weeks is shown below:
= Earning per hour × number of hours works per day × number of days works per week × number of weeks
= $16.85 × 7 × 4 × 4
= $1,887.20
Hence, the gross monthly income for 4 weeks is $1,887.20
1.5 is a rational number.it can be written as the ratio 3/2
Answer:
Step-by-step explanation:
Since we have an x under that radical, we have to get it out from under there. To do that, do the opposite of the square root, which is to square. But because this is an equation, you have to do the same thing to both sides. Doing this gives you
Get everything on one side and set the quadratic equal to 0 and solve for x:
Factor this into 2 factors of (x - 3)(x - 3) = 0. As you can see they are both the same, so x - 3 = 0 and x = 3. That's your answer. x = 3.
