The polynomial p(x) has leading coefficient a and degree m, and the polynomial q(x) has leading
coefficient b and degree n. Suppose that m>n, what
is the leading coefficient and degree of p(x)+q(x)?
Leading coefficient =a , degree=m
Leading coefficient =a , degree=m+n
Leading coefficient =a + b, degree=m
Leading coefficient =a + b, degree= m +n

This is too long-standing now get out

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
