Help i need help please

The coefficient would be 18. The exponent for g would be 18. The exponent for h would be 9.

Add the exponents of the same variable and multiply the coefficents.

a  18

b 18

c 9

Step-by-step explanation:

6 g^4 h^3 * g^10 h^5  * 3 g^4 h

We know that a^b*a^c = a^(b+c)

So rewriting

6 g^4 h^3 * g^10 h^5  * 3 g^4 h^1

6*3  g^(4+10+4) h^(3+5+1)

18 g^18 h^9

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5
