2. Multiply and find the product of the following: (a) (-2) × (5) × (-7) (b) 6 × (8) × (-9) (c) (-5) × (-6) × (-3) × (2) (d) (-1) × (9) × (-9) × (3) 3. Write the exponent of each of the following: (a) (7)^{11} (b) (-6)^{3} (c) (1)^{20} (d) (5)^{7}

Let's solve the problem step by step.

Multiply and find the product:

(a) ( − 2 ) × ( 5 ) × ( − 7 )

First, multiply − 2 by 5 : − 2 × 5 = − 10
Then, multiply the result by − 7 : − 10 × − 7 = 70
Therefore, the product is 70 .

(b) 6 × ( 8 ) × ( − 9 )

First, multiply $6 by $8 : 6 × 8 = 48
Then, multiply the result by − 9 : 48 × − 9 = − 432
Therefore, the product is − 432 .

(c) ( − 5 ) × ( − 6 ) × ( − 3 ) × ( 2 )

First, multiply − 5 by − 6 : − 5 × − 6 = 30
Next, multiply the result by − 3 : 30 × − 3 = − 90
Finally, multiply the result by 2 : − 90 × 2 = − 180
Therefore, the product is − 180 .

(d) ( − 1 ) × ( 9 ) × ( − 9 ) × ( 3 )

First, multiply − 1 by 9 : − 1 × 9 = − 9
Next, multiply the result by − 9 : − 9 × − 9 = 81
Finally, multiply the result by 3 : 81 × 3 = 243
Therefore, the product is 243 .


Write the exponent of each of the following:

(a) ( 7 ) 11

The exponent here is 11 .

(b) ( − 6 ) 3

The exponent here is 3 .

(c) ( 1 ) 20

The exponent here is 20 .

(d) ( 5 ) 7

The exponent here is 7 .

I hope this detailed explanation helps you understand how to multiply numbers and identify exponents.
