((2x^9)(y^n))((4x^2)(y^10))=(8x^11)(y^20)

tino4ka555 [31]

We are given

$((2x^9)(y^n))((4x^2)(y^{10}))=(8x^{11})(y^{20})$

Firstly, we simplify left side

Left side is

$((2x^9)(y^n))((4x^2)(y^{10}))$

we will make all x terms together

and y terms together

$(2x^9)(4x^2)(y^n)(y^{10})$

$2\times 4(x^9)(x^2)(y^n)(y^{10})$

$8(x^9)(x^2)(y^n)(y^{10})$

we can multiply left side by using exponent rule

$a^m\times a^n=a^{m+n}$

$8(x^{9+2})(y^{n+10})$

$8(x^{11})(y^{n+10})$

now, we can set them equal

$(8x^{11})(y^{n+10})=(8x^{11})(y^{20})$

Since, both sides have x,y and 8

and both are equal

so, their exponent must be equal

so, exponent of y must also be equal

we get

$n+10=20$

$n=10$ ................Answer

Cloud [144]

8 - 1/3x = 16
⇒ -1/3x= 16-8
⇒ -1/3x= 8
⇒ x= -24

The final answer is -24~
