Or, 1/10(135 × 48 + ? × 32) = 728

Or, (135 × 48 + ? × 32) = 7280

Or, (6480 + ? × 32) = 7280

Or, ? × 32 = 7280-6480

Or, ? × 32 = 800

Or, ?  = 800/32

Or, ? =25 is the Correct Answer.

1/10 gets cancelled

Or, (35× sixteen + ? × 18)= (50 × 31)

Or, (560 + ? × 18)= (1550)

Or, ? × 18= 1550-560

Or, ? × 18= 990

Or, ? × 18= 990/18

Or, ? = 55 is the Correct Answer.

8) 4⁷ ÷ 16⁴ × √16 = ?

Answer & Explanation:

4⁷ ÷ 16⁴ × √16

[Since:√16=√(4×4)=4 ]

= 4⁷ / (4×4)⁴ × 4

= 4⁷ / (4²)⁴ × 4

= 4⁷ / 4^2×4 × 4

= 4⁷ / 4⁸ × 4
