Answer:
-343
Step-by-step explanation:
Given the expression:
You will notice that the terms in the numerator and denominator have the same base (-7).
This makes it very easy to simplify by applying the division law of indices.
Therefore:
Answer:
The number in its standard form is
Step-by-step explanation:
The standard form of a number is just a simplified way of writing numbers {especially large ones} that has been agreed on by mathematicians all over the world.
To write a number in standard form we need to first of all check this:
1. Is the number greater than zero or not?
In our problem, 713.49 is clearly greater than zero so we can move on to the next step.
2. The next step is to make sure that we move the decimal point to a position where it will make the value of the number less than 10.
We can do this by moving the decimal point two times to the left. This makes the number 7.1349 which is less than 10.
3. The final step is to count the number of times that you moved the decimal point to make the number less than 10.
In our case, it is 2 times. We then use this number as the power.
Thus the answer will be
This is the concept of algebra:
y=^3sqrt(x-5) can be written as:
y=(x-5)^(1/3)
Given that y=0 at the point x=5, that is:
when x=5 then
y=(5-5)^(1/3)
y=0^(1/3)
y=0
from the above we conclude that the domain is:
{x∈ R: x≥5}
That means that the domain is all real numbers greater than or equal to 5.
