Write out the expression 2 - (2x-7)^2. That's it.
But if you want to go further and remove the parentheses, first expand (2x-7)^2: (2x-7)^2 = 4x^2 - 28x + 49,
and then subtract this result from 2:
2 - (4x^2 - 28x + 49) (It's important to use parentheses here)
Now, following the distributive property of multiplication, remove the parentheses:
2 - 4x^2 + 28x - 49
Combining the constants, we get the final answer: - 4x^2 + 28x - 47
LOL...it took me a few seconds to realize what you were attempting to express...which is the fifth root of 13 cubed...
(13^3)^(1/5) rule: (a^b)^c=a^(b*c)
13^(3*1/5)
13^(3/5)
4 the answer
hope it helped
Answer:
I did the math and checked it im pretty sure this is the right answer
Answer:
The answer is true.
Step-by-step explanation:
Sample methods that embody random sampling are often termed probability sampling methods.
Yes this is a true statement.
Random sampling means picking up the samples randomly from a whole population with each sample having an equal chance of getting selected.
For example- selecting randomly 10 students from each class of a school, to survey for the food quality in school's cafeteria.
And this is a type of probability sampling methods. Other types are stratified sampling, cluster sampling etc.
