whenever you're multiplying terms that have exponents you multiply the coefficients and add their exponents:
Step-by-step explanation:
I think the answer to your first question should be:
30a²b - 30ab²
Your second answer is good
whenever you're multiplying terms that have exponents you multiply the coefficients and add their exponents:
for example, 6a²b³c x 2abc = 6(2)(a²)(a)(b³)(b)(c)(c)
= 12a³b⁴c²
Answer:

Answer:
c
Step-by-step explanation:
Known :
h = 10
d = 3
Asked :
V = ...?
Answer :
V = ¼πd²h
= ¼ × 3.14 × 3² × 10
= ¼ × 3.14 × 9 × 10
= <u>7</u><u>0</u><u>.</u><u>6</u><u>5</u>
