Answer 1
Answer:

The radical expression is an expression with rational exponents that can be written after applying the properties of the integer exponent.

What is an integer exponent?

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that the expression:

= \rm (\sqrt[5]{x} )^7

As we know, the expression can be defined as the combination of constants and variables with mathematical operators.

From the properties of the integer exponent:

Integer exponents are exponents that should be integers. It may be a positive or negative number

Applying the properties of the integer exponent:

= \rm x^{(1)/(5)}^(* 7)

= \rm x^{(7)/(5)}

Thus, the radical expression is an expression with rational exponents that can be written after applying the properties of the integer exponent.

What is the additive inverse of the polynomial? -7y^2+x^2y-3xy-7x^2

Answers

Answer:

Additive inverse is  (7y² - x²y + 3xy + 7x²).

Step-by-step explanation:

Let the additive inverse of the given polynomial be Y.

Therefore as per definition of additive inverse of any polynomial the addition of a polynomial and additive inverse of any polynomial is always zero.

So Polynomial + additive inverse polynomial = 0

(-7y² + x²y - 3xy - 7x²) + Y = 0

Y = -(-7y² + x²y - 3xy - 7x²) = (7y² - x²y + 3xy + 7x²)

So the additive inverse of the polynomial will be (7y² - x²y + 3xy + 7x²).

Answer:

The answer is A

Step-by-step explanation:

The additive inverse is basically the opposite symbol for the numbers.

So, therefore:

What is the additive inverse of the polynomial?

-7y^2 + x^2y - 3xy - 7x^2

The answer to this would be

7y^2 - x^2y + 3xy + 7x^2

29 - 7g = 3g + 9 =

PLEASE HELP!

Answers

Answer:

g=2

Step-by-step explanation:

29 - 7g = 3g + 9  

move all the terms to the left, that means subtract it and set it equal to zero

29-7g-(3g+9)=0

Get rid of the parenthesis by grouping like terms together.

-7g-3g-9+29=0

Add all the numbers and variables.

-10g=-20

Divide by -10 on both sides

-10g/-10=-20/-10

Which gives you g=2

The product of 3 and a number is 12 more than the sum of the number and 26. What is the number?

Answers

The product of three and a number (3n) is 12 more than (=12 +) the sum of the number and 26 (n + 26). Put all of those together.

2n = 12 + n + 26     Combine like terms.  (12 + 26)
2n = 28 + n             Subtract to get the variables together. (2n - n)
n = 28
