Answer 1

$sqrt{a^5b} + frac{3}{4a} sqrt{a^7b}-frac{3}{4a^2} sqrt{a^9b} = a^2 sqrt{ab} + frac{3a^3}{4a} sqrt{ab}-frac{3a^4}{4a^2} sqrt{ab} =\ \ a^2 sqrt{ab} +0.75a^2 sqrt{ab} +0.75a^2 sqrt{ab}=a^2 sqrt{ab}$

$sqrt{c^7} +8c sqrt{c^5} -11c^2 sqrt{c^3} =c^3 +8cc^2sqrt{c} -11c^2csqrt{c} = -2c^3sqrt{c}$

$n sqrt{m^4n^3} +m^2 sqrt{n^5} -3n^2 sqrt{m^4n} = \ \ nm^2n sqrt{n} +m^2n^2sqrt{n} -3n^2m^2sqrt{n} =-n^2m^2sqrt{n}$

$sqrt{x^7y^8} -5x^3y sqrt{xy^6} +6xy^2 sqrt{x^5y^4} = \ \ x^3y^4 sqrt{x} -5x^3yy^3 sqrt{x} +6xy^2x^2y^2 sqrt{x} =2x^3y^4 sqrt{x}$
