Question

0.76×0.76+2×0.76×0.24+0.24×0.24

Answer 1

1) arrange the question
(0.76×0.76×0.76+0.24×0.24×0.24)+2
(a3+b3)=(a+b) (a2-ab+b2)
(0.76)3 + (0.24)3
(0.76+0.24) ((0.76)2-0.76×0.24+(0.24)2)
1 (0.5776-0.1824+0.0576)
1×0.4528+2
0.4528+2
2.4528

Answer 2

Answer:

The answer is 1.

Step-by-step explanation:

We have,

We have,0.76 × 0.76 + 2 × 0.76 × 0.24 + 0.24 × 0.24

We have,0.76 × 0.76 + 2 × 0.76 × 0.24 + 0.24 × 0.24= (0.76 + 0.24)2 [a2 + b2 + 2ab = (a + b)2]

We have,0.76 × 0.76 + 2 × 0.76 × 0.24 + 0.24 × 0.24= (0.76 + 0.24)2 [a2 + b2 + 2ab = (a + b)2]= (1.00)2 [Where a = 0.76 and b = 0.24]

We have,0.76 × 0.76 + 2 × 0.76 × 0.24 + 0.24 × 0.24= (0.76 + 0.24)2 [a2 + b2 + 2ab = (a + b)2]= (1.00)2 [Where a = 0.76 and b = 0.24]= 1
