Explanation

√144 = 12, √25 = 5 →

4×12 + 3×5 = 48 + 15 = 63

Explanation

Subtract (3x) from both sides: (7x-3x=3x+12-3x)

(4x=12)

Divide both sides b y(4): {4x}/{4}=12/4

x=3

Explanation

(0.2)³ = 0.008 → 4 + 0.008 = 4.008

Explanation

Let the unknown number = x
(1/5 + x)/2 = 1/4 → Multiply both sides by 2:
1/5 + x = 1/2 → x = 1/2 - 1/5 = (5−2)/10 = 3/10 = ⅖

Explanation

 Add 2, then multiply by 2 →

7+2=9

9×2=18

18+2=20

20×2=40

40+2=42

42×2=84
