50 points what is 3x^-4(8x+12x) simplified??

60

x^3

Step-by-step explanation:

3x^-4 (8x + 12x)

apply exponential rule:

= 3 * 1/x^4 *(8x + 12x)

add similar elements

= 3 * 20 * (1/x^4) x

multiply fractions:

= 1 * 3 * 20x

        x^4

simplify:

= 60x

    x^4

finally = 60

             x^3

Collect like terms

3x^-4×(8x+12x)

=3x^-4 * 20x

=60x^-3

=60 * 1/x^3

i dont know and i dont care for math bc it is a stupied subject

step-by-step explanation:

the answer is 99.
