Answer 1

Here are the answers:

1) a^2 = 225 → a = ±15

2) b^3 = −125 → b = −5

3) 3(4x − 2) = 1 → x = 7/12

4) 5m − 5m − 12 = 14 − 2 → No solutions (Zero)

5) 8x − 3x − 1 = −2 + 16 → One solution (x = 3)

6) −6(3g + 2) → −18g − 12

7) 2(3y + 7 + 5) = 196 − 16 → y = 26

8) −a − 2 = −3a + 8 → a = 5

9) 3x − 7 = 4 + 6 + 4x → One solution

10) 7p + 4 = −p + 9 + 2p + 3p → 3p = 5

11) 3x + 2(x − 9) = 8x + x − 14 → x = −1

12) −4.3z = 4.3z − 7.68 → z = 7.68/8.6 = 192/215 ≈ 0.893

13) (4/5)n − (1/5) = (2/5)n → n = 1/2
