Question

Let a = 4/5 and c = -2/7. Then solve (a xa xa+cxc-a) / (c-a)​

Answer 1

Answer:

0.2 or 632 / 3325

Step-by-step explanation:

a = 4/5 and b = -2/7

ATQ,

[(4/5)3 + (-2/7)2 - 4/5] / (-2/7 - 4/5)

[64/125 + 4/49 - 4/5] / [-38/35]

[3136 + 500 - 4900/6125] / [-38/35]

[-1264/6125] / [-38/35]

632/3325

or 0.1900 ≈ 0.2
