0 If A3 B3 3ab 7 Then Find Value Of A B A B 8 Iven A B 1 Then Fi If ` [a 4 3b8 6]= [2a 2b 2 8a 8b]` , write the value of `a 2b` . text solution verified by experts given: ` [ (a 4, 3b), (8, 6)]= [ (2a 2,b 2), ( 8,a 8b)]` now both matrices are equal then `implies a 4=2a 2` `implies a−2a=2−4` `implies −a=−2` hence `a=2 . (i)` also, `implies 3b=b 2`. Given: [ (a 4, 3b), (8, 6)]= [ (2a 2,b 2), ( 8,a 8b)] now both matrices are equal then implies a 4=2a 2 implies a−2a=2−4 implies −a=−2 hence a=2 . (i) also, implies 3b=b 2 implies 3b−b=2 implies 2b=2 hence b=1 . (ii) from (i) and (ii) implies a−2b=2−2 (1) implies a−2b =2−2 implies a−2b=0.
10 If 2a 3b 6c 0 Then Find The Value Of 8a3 27b3 216c3 Filo Question if [𝑎 4 3 𝑏 8 − 6] = [2 𝑎 2 𝑏 2 8 𝑎 − 8 𝑏] , write the value of a − 2 b. Substituting the values of a and b in. a – 2b = 2 – 2 (1) ⇒ a – 2b = 2 – 2. ⇒ a – 2b = 0. thus, the value of a – 2b is 0. Question if a 4 3 b 8 6 = 2 a 2 b 2 8 a 8 b, write the value of a − 2b. solution a 4 3 b 8 6 = 2 a 2 b 2 8 a 8 b corresponding elements of equal matrices are equal. ∴ a 4 = 2 a 2 and 3 b = b 2 ⇒ 4 2 = 2 a a and 3 b b = 2 ⇒ a = 2 and 2 b = 2 ⇒ a = 2 and b = 1 ∴ a 2 b = 2 2 = 0 suggest corrections. To solve math problems step by step start by reading the problem carefully and understand what you are being asked to find. next, identify the relevant information, define the variables, and plan a strategy for solving the problem.
F Find The Value Of 2a 3b 5a 7b 8 If A 3i 4j And B 2i 4j Then Question if a 4 3 b 8 6 = 2 a 2 b 2 8 a 8 b, write the value of a − 2b. solution a 4 3 b 8 6 = 2 a 2 b 2 8 a 8 b corresponding elements of equal matrices are equal. ∴ a 4 = 2 a 2 and 3 b = b 2 ⇒ 4 2 = 2 a a and 3 b b = 2 ⇒ a = 2 and 2 b = 2 ⇒ a = 2 and b = 1 ∴ a 2 b = 2 2 = 0 suggest corrections. To solve math problems step by step start by reading the problem carefully and understand what you are being asked to find. next, identify the relevant information, define the variables, and plan a strategy for solving the problem.
