Question

Find the value of. Step_by_Step explanation.​

Answer 1

Step-by-step explanation:

Given :-

(6a³)×(-7a²b²)×(1.1ab)

To find :-

Find the value of the expression at a = 1 and b = 0.5 ?

Solution :-

Method-1:-

Given expression is (6a³)×(-7a²b²)×(1.1ab)

=> (6×-7×1.1) × (a³×a²×a)×(b²×b)

=> -46.2×a⁶×b³

=> -46.2a⁶b³

Now ,

Put a = 1 and b = 0.5 then

=> -46.2×1⁶×(0.5)³

=> -46.2 × 1 × 0.125

=> -46.2×0.125

=> -5.775

Method-2:-

Given expression is (6a³)×(-7a²b²)×(1.1ab)

Put a = 1 and b = 0.5 then

=> (6×1³)×(-7×1²×(0.5)²)×(1.1×1×0.5)

=> (6×1) ×(-7×1×0.25)×(11×0.5)

=> 6×-1.75×5.5

=> -5.775

Answer:-

The value of the given expression is -5.775

Answer 2

Step-by-step explanation:

(6a³) × (-7a²b²) × (1.1ab)

(6 × 1³) × ( -7 × 1²× 0.5²) × (1.1×1×0.5)

6× -1.75 × 0.55

-5.775
