To simplify this expression, we can add the exponents:

u^(3+1+5) = u^9
Multiply.
9y(−3y^8)
SIMPLIFY AS MUCH AS POSSIBLE
To simplify this expression, we can multiply the coefficients and add the exponents:

9 * -3 = -27
y^1 * y^8 = y^(1+8) = y^9

Therefore, the simplified expression is -27y^9.
Factor
−15a^3-12a^2
To factor the expression −15a^3 - 12a^2, we can first find the greatest common factor (GCF) of the two terms. The GCF of -15 and -12 is 3. The GCF of a^3 and a^2 is a^2.

So, we can factor out the GCF from each term:

-15a^3 - 12a^2 = 3a^2(-5a - 4)

Therefore, the factored form of the expression −15a^3 - 12a^2 is 3a^2(-5a - 4).
