Help which expression is equivalent to this one? cuhhhhh.....!!

Answer:
3^ 6
Step-by-step explanation:
3^-2 * 3^8
We know that a^b * a^c = a^(b+c)
3^(-2+8)
3^ 6
Answer: [tex]3^{6}[/tex]
Step-by-step explanation: Since these two powers have the same base of 3, we can multiply them together by adding their exponents.
So [tex]3^{-2}[/tex] [tex]x[/tex] [tex]3^{8}[/tex] is [tex]3^{6}[/tex].
This idea is called the product rule.
