What is the simplified form of the expression? c^9d^-7/c^14d^-10

Just as same-base exponents can be added when multiplied, you should subtract the exponent when the numbers are being divided:

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
