Prove that the inequality (a+1)·(a+1)>(a−1)·(a−1) is not true for some values of a.
Effectus [21]

Explanation:

Consider the case a = -1. Then the expression becomes ...

  (-1+1)(-1+1) > (-1-1)(-1-1) . . . . test case

  0·0 > (-2)(-2) . . . . . simplified a bit

  0 > 4 . . . . . . . . NOT TRUE

_____

If we subtract the right side from both sides, the inequality becomes ...

  (a+1)(a+1) -(a-1)(a-1) > 0

  a² +2a +1 -(a² -2a +1) > 0

  4a > 0

  a > 0

The inequality is only true for positive values of "a". For a ≤ 0, the inequality will not be true.

Answer:

The solution for x is 8.911

Step-by-step explanation:

Given expression as :

7^{x} = 18^{6}

<u>Taking Log both side</u>

Log 7^{x} = Log 18^{6}

<u>From Log property </u>

Log a^{b} = b Log a

So, x Log 7 = 6 Log 18

Or, x × 0.845 = 6 × 1.255

Or , x × 0.845 = 7.53

∴  x = \frac{7.53}{0.845}

I.e x = 8.911

Hence The solution for x is 8.911    Answer
