Answer:

10+9x can't be combined to make a number

Step-by-step explanation:

This is because the 10 doesn't have the variable x so we can't combine them together

If the 10 had an x beside it, it would've become 19x, but it doesn't so it stays as is

Plz answer its easy math.

Answer:

B and E

Step-by-step explanation:

The rules of indicies states:

$x^{a}$ ÷ $x^{b}$ = $x^{a-b}$

So $3^{-8}$ ÷ $3^{-4}$ = $3^{-8 - - 4}$ = $3^{-4}$

So that means B is one of the correct answers.

To find the other correct value, you can divide the two fractions as stated in the question:

$3^{-8}$ by $3^{-4}$ = $\frac{1}{81}$

81 is equivalent to 3⁴

So that means E is also correct.
