Classify the number √23 as rational or irrational. Options: a) Rational b) Irrational

Answers

Answer 1
Answer:

Answer:

b

Step-by-step explanation:

a rational number can be expressed in the form

(a)/(b) where a and b are integers

√(23) has no factors which are perfect squares and so cannot be expressed in this form.

then √(23) is irrational

Choose the correct classification of 5x + 3x4 − 7x3 + 10 by number of terms and by degree.Third degree polynomial
Fourth degree polynomial
Sixth degree polynomial
First degree binomial

Answers

Answer:

Fourth degree polynomial

Step-by-step explanation:

Given is an algebraic expression with 4 terms as

5x+3x^4-7x^3+10

First let us arrange these terms in the descending powers of x.

We get

3x^4-7x^3+5x+10

is the standard way of representing any polynomial.

This is a polynomial because x has powers only as non negative integers.

The degree is 4 since the leading term or highest degree term has degree 4.

This is a polynomial as this got more than 3 terms after simplification.

Hence Option B is the answer.

Answer:

Fourth degree polynomial.

Step-by-step explanation:
