is 5xcube-4the square rootof 2x+x a polynomial

Sagot :

NO, IT'S NOT.

The simplified term:
[tex]-4 \sqrt{2x+6} = - \sqrt{16(2x+6)} [/tex]

Therefore this term has a fractional exponent,
[tex] \sqrt{2x+x} = (2x)^{ \frac{1}{2} } + x^{ \frac{1}{2} } [/tex]

BY DEFINITION OF POLYNOMIAL BY MATHEMATICIANS, it has to meet the following conditions:

IN SIMPLIFIED FORM:
1)  no fractional / negative exponent
2) no variable as denominator in any term.

The given has a fractional exponent.  When in simplified form, a variable is left under the radical symbol, the expression is not a polynomial.

So, the given expression IS NOT A POLYNOMIAL.
