Answer:

[tex]6x^{13}y^{17}[/tex]

Step-by-step explanation:

We need to multiply

[tex]3x^8y^9.2x^5y^8[/tex]

We know the exponent rule of multiplication:

[tex]x^a y^b . x^cy^d = x^{a+c}y^{b+d}[/tex]

If the bases are same the powers are added.

So,

[tex]=3*2 *x^8*x^5*y^9*y^8\\=^{8+5}y^{9+8}\\=6x^{13}y^{17}[/tex]

So, the answer is:

[tex]6x^{13}y^{17}[/tex]
