Answer:

1. 5m - 6

5(7) - 6

35 - 6

= 29

2. 4m + 1

4(7) + 1

28 + 1

= 29

3. r/t

8/2 ÷ 2/2

= 4

4. mt

7 × 2

= 14

5. 5r + 2m

5(8) + 2(7)

40 + 14

= 54

6. (rm)³

(8 × 7)³

56 × 56 × 56

3,136 × 56

= 175,616

7. 3m² - 5

3(7)² - 5

3 × 49 - 5

147 - 5

= 142

8. 2mr / t³

2 × 7 × 8 / 2³

14 × 8 / 8

112/8 ÷ 8/8

= 14

9. (m - r)³ + rt

(7 - 8)³ + 8 × 2

(-1)³ + 16

-1 + 16

= 15

10. (r + t) - (r - t)

(8 + 2) - (8 - 2)

10 - 6

= 4

Answer:

1. ) 5(7)-6= 35-6=29

2.) 4(7)+2=28+2=30

3.) 8/7=1.14 or 1 1/7

4.) (7)2=14

5.) 5(2)+2(7)=10+14=24

6.) ((8)7)^3=512(343)=175,616

7.) 3(7)^2-5=3(49)-5=147-5=142

8.) 2(7)(8)/2^3=112/8=14

9.) (7-2)^3+8(2)=(343-8)+16=335+16=351

10.). (8+2)-(8-2)=(10)-(6)=10-6=4
