Explanation

When 39 is divided by 4:

• 4 × 9 = 36, remainder = 39 − 36 = 3
• When 39 is divided by 9:
• 9 × 4 = 36, remainder = 39 − 36 = 3

So in both cases remainder is 3, which satisfies the condition.

Explanation

Look at the pattern: each term × 3  

2 → 6 → 18 → ? → ? → 486  

So 18 × 3 = 54

54 × 3 = 162  

162 × 3 = 486  

Full sequence: 2, 6, 18, 54, 162, 486  

Now "4th term from the last"  

Last = 486, 2nd last = 162, 3rd last = 54, 4th last = 18.

Explanation

When a power is raised to another power, we multiply exponents:

(m¹⁄₃)³⁄₅ = m^(1/3 × 3/5) = m¹⁄₅

(n⁻²)³⁄₅ = n^(-2 × 3/5) = n⁻⁶⁄₅

So the simplified form is m¹⁄₅ n⁻⁶⁄₅.
