The degree of the polynomial 6x2 - 4x3 + x - 1 is 2. ____5.4means to multiply 3 by itself 4 times. ____6. The degree of any nonzero constant monomial is 0. ____7. Some polynomial contains negative number exponents on the variables. ____8. The value of a constant can be changed. ____9. The degree of a monomial is the leading coefficient of that term. ____10. Numerical coefficient is the number factor in an algebraic term.​

Answer 1

Answer:

4x2 – 3x + 7

⇒ 4x2 – 3x + 7x°

∵ All the exponents of x are whole numbers.

∴ 4x2 – 3x + 7 is a polynomial in one variable.

(ii)

∵ All the exponents of y are whole numbers.

∴ is a polynomial in one variable.

(v) x10 + y3 + t50

∵; Exponent of every variable is a whole number,

∴ x10 + y3 + t50 is a polynomial in x, y and t, i.e. in three variables.
