What is the simplified form of the ninth root of x times the ninth root of x times the ninth root of x times the ninth root of x
Tomtit [17]
Let's convert the task into an example, simplifyng which will make us able to get the answer.
So, according to the task: \sqrt[9]{x} *  \sqrt[9]{x} *  \sqrt[9]{x} *  \sqrt[9]{x} 

=   \sqrt[1/ 9 ]{x} *  \sqrt[1/9]{x} *  \sqrt[1/9]{x} *  \sqrt[1/9]{x}

Now we can simplify: \sqrt[1/9]{x} + 1/9+1/9+1/9

= x^{4/9}

So the answer is  <span>C:x to the four ninths power</span>

Answer:

Option A, B, and D are true.

Explanation:

A coefficient is the number that is being multiplied by a variable. For example, in 7b, 7 would be the coefficient.

Terms are the numbers used in the equation. For example, in 3 + 2, 3 and 2 would be the terms.

3n and 5m are not coefficients as there are variables included. 3n and 5m are examples of a variable.

A constant is a number that is not multiplied by a variable. For example, in 8x + 3 + 2b, 3 would be the constant.

Hope this helped :)

Mama L [17]

Answer:

z = 120º

Step-by-step explanation:

t + 2t + t + 2t = 360º

60 + 2(60) + 60 + 2(60) = 360

t = 60

2t = z

z = 120º

This is all based on the fact there there are 360º in a quadrilateral.
