b) √150x$^4$y²-√24x²y$^4$+√96x³y³=
c) 36x$^5$y³z²-27x$^4$y²z³-63x³y³z³=
d) 75x²y³z$^4$-50x³y²z²-100x$^4$y³z²=

Answer 1

a) √32x²y²-√50x³y²+√72x²y³-√200x³y³=
=4√2x²y²-5√2x³y²+6√2x²y³-10√2x³y³=
=√2x²y²(4-5x+6y-10xy)

b) √150x⁴y²-√24x²y⁴+√96x³y³=
=5√6x⁴y²-2√6x²y⁴+4√6x³y³=
=√6x²y²(5x²-2y²+4xy)

c) 36x⁵y³z²-27x⁴y²z³-63x³y³z³=
=9x³y²z²(4x²y-3xz-7yz)

d) 75x²y³z⁴-50x³y²z²-100x⁴y³z²=
=25x²y²z²(3yz²-2x-4x²y)
