Question

II. Study the following pattern and complete t
4) 1, 3, 10, 21, 64, 129,
5) 91 x 44 = 4004
91 x 55 = 5005
91 x 66 = 6006
simplify the following using the propertie
162 x 19 + 13 x 162
2175 x 79 - 69 x 2175​

Answer 1

Answer:

4) 1, 3, 10, 21, 64, 129,388

162*19+13*162=162(19+13)=162*32=5184

2175*79-69*2175=2175(79-69)=2175*10=21750

Step-by-step explanation:

1*2+1=3

3*3+1=10

10*2+1=21

21*3+1=64

64*2+1=129

129*3+1=388

For both questions, taking common on both cases,

162*19+13*162=162(19+13)

Taking 162 as common number

2175*79-69*2175=2175(79-69)

Taking 2175 as a common number

Answer 2

Answer:

Step-by-step explanation:

1*2+1=3

3*3+1=10

10*2+1=21

21*3+1=64

64*2+1=129

129*3+1=388
