C. 64

Rewrite the logarithm:

8=x^.5

Solve by raising both sides of the equation to the power of the inverse (in this case, the inverse of .5, which is 2):

8^2=x^(.5*2)

64=x

When a number x is divided by 24 the remainder is 23 and when it is divided by 36 the remainder is 35. Find the least number tha
Snezhnost [94]

Answer:

7 is the answer. If a number can be divided by 36 then it can also be divided by 12 which is 3*12 therefor the remainder will be 19-12 which is 7. When 19 is divided by 36, the remainder is 19 and so 19 must be a number. When 19 is divided by 12 the remainder is 7.

This is a full assignment I’m struggling on if someone can answer them all and get most correct I will give you Brainliest for y
Effectus [21]

Answer:

Step-by-step explanation:

a) 1) Polynomial is closed under addition. In polynomial addition, only the coefficient change and variables and it powers does not change.

Example: Add 3x² - 2x + 7  and -2x² - 5x + 3

3x² - 2x + 7 - 2x² - 5x + 3 = 3x² -2x² - 2x - 5x + 7 + 3

= x² - 7x + 10

2)Polynomial    is closed under addition. In polynomial subtraction, only the coefficient change and variables and it powers does not change.

Example: Subtract 3x - 2 from 4x + 2

4x + 2 - (3x - 2) = 4x + 2 - 3x + 2  = 7x + 4

3) Polynomial is closed under multiplication. In this, exponents of the variables are added according to the exponent rule. As the exponent of polynomials are whole numbers and whole numbers are closed under addition, the result will be a whole number.

-2x³ * 3x² = -3*x^{3+2}=-3x^{5}

4) Polynomial is not closed under multiplication. In division, we may get a negative exponent. So, it is not closed under division.

\dfrac{x^{4}}{x^{9}}=x^{4-9}=x^{-5}\\\\x^{-5} \ is \ not \ a \ polynomial.

                                 Addition        subtraction  multiplication   Division

Natural numbers          yes             not closed    Yes                   Not closed

Integers                        Yes                 Yes              Yes                   not closed

Rational numbers         Yes                 Yes              Yes                     not closed

Irrational numbers       not closed   not closed   not closed   not closed
