Answer 1

Given :-

• a = - 2

• b = 1

• c = 2

_____________________

iii) 4a²b - 3/2ab² + 1/2abc

=> 4. (-2)². (1) - 3/2. (-2) . (1)² + 1/2 . (-2) . (1) . (2)

=> 16 + 3 - 2

=> 17

iv) c² - b³ + 1/4a³

=> (2)² - (1)³ + 1/4 . (-2)³

=> 4 - 1 -2

=> 1

Answer 2

Answer:

Step-by-step explanation:

ques 1.)4a^2b-3/2ab^2+1/2abc

(8a^2b-3ab^2+abc)/2(take l.c.m)

put the values a,b,c in expression

(8(-2^2)(1)-3(-2*1^2)+-2*1*2)/2

(8*4-6-4)/2

32+6-4/2

34/2

17 ANS.

ques 2.)c^2-b^3+1/4a^3

take l.c.m

4c^2-4b^3+1/4a^3

then,put the values of a,b,c;

4*2^2-4^3+1/4*-2^3

4*4-64+1/4-8

16-64-2

16-66

-50
