Question

1) If a = -1 and b = 8, find the value of the following algebraic expressions: b (ii) 3ab - 12 (iii) +9 (iv) 4ba- 5 (v) 10 - bab du in each of the statements and make algebraic equations. a (i) 7ab-9​

Answer 1

Answer:

(i)7ab-9

now, putting values:[7×(-1)×8]-9= -56-9= -65

(ii) 3ab-12

now,putting values: 3×(-1)×8-12= -34-12=-46

(iv) 4ba-5

now, putting values : [4×8×(-1)]-5= -32-5= -73
