Question

16x^4y^2(9x^3y^4) fully simply

Answer 1

Explanation:

2 x(4−3xy^2)/y

Answer 2

`=144x^7y^6`

Explanation:

`16x^4y^2\left(9x^3y^4\right)\\\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^(b+c)\\x^4x^3=\:x^(4+3)\\=16y^2\cdot \:9x^(4+3)y^4\\\mathrm{Add\:the\:numbers:}\:4+3=7\\=16y^2\cdot \:9x^7y^4\\\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^(b+c)\\y^2y^4=\:y^(2+4)\\=16\cdot \:9x^7y^(2+4)\\\mathrm{Add\:the\:numbers:}\:2+4=6\\=16\cdot \:9x^7y^6\\\mathrm{Multiply\:the\:numbers:}\:16\cdot \:9=144\\=144x^7y^6`
