Interpreting the variable as m: No. sqrt(m) − 7 = m^(1/2) − 7 is not a polynomial in m because it has the noninteger exponent 1/2. Polynomials in m must have only nonnegative integer exponents.
If you instead set t = √m, then the expression is t − 7, which is a polynomial in t of degree 1.
If you instead set t = √m, then the expression is t − 7, which is a polynomial in t of degree 1.
