Question 9 (Essay Worth 2 points)

Part 1: Explain, using complete sentences, how to simplify the expression below.
Part 2: What is the simplified expression?

(3x3y4)(2x2y6)

Answer 2

Question 1
Its muliplication so, (3d=d3)\[3d \times 5d= (3 \times 5)d\]\[ (3 \times 5)d=15d\]

Answer 3

Question 3
The coefficients will multiply 2*2=4.
Therefore xy4 is the answer.

Answer 4

Question 5
(3d)5
15d

Answer 5

Question 7
(b5)4
b20

Answer 6

question 8 is same as question 1

Answer 7

Question 9
Part 1
(just open the brackets)
Part 2
(3x3y4)(2x2y6)
3*3*4=36 6*2*2=24
(36xy) (24xy)
24*36=864\[364x ^{2}y ^{2}\]because x*x and y*y
