Answer:

[tex]a=6[/tex]

[tex]b=7[/tex].

Step-by-step explanation:

The given exponential equation is;

[tex](5x^a)(bx^2)=35x^8[/tex]

We multiply out to obtain;

[tex]5b(x^a)(x^2)=35x^8[/tex]

Recall and use [tex]a^m\times a^n=a^{m+n}[/tex]

[tex]5bx^{a+2}=35x^8[/tex]

For the RHS  to equal to the LHS,then

[tex]5b=35[/tex]  and [tex]a+2=8[/tex].

[tex]b=\frac{35}{5}[/tex]  and [tex]a=8-2[/tex]

[tex]b=7[/tex]  and [tex]a=6[/tex].
