Option A
17.99^2 – 14.05^2 + (2343.75 + 81.55) ÷ ? = 229
(18)^ 2 − (14)^ 2 + (2350 + 80) ÷ ? = 230
=> 324 – 196 + (2430) ÷ ? = 230
=> 2430 ÷ ? = 230 – 130
=> 2430 ÷ ? = 100
=> ? = 2430/100 = 24.3 == 24

2. 7^ 2.3 × 7^( 2×4.7) × (7 × 9)^3.4 × (9^2 )^ 5.85 = 63^?

Option D
7^ 2.3 × 7^( 2×4.7) × (7 × 9)^3.4 × (9^2 )^ 5.85 = 63^? => 7^(2.3+9.4+3.4) × 9^(3.4+11.70) = (63)^?
=>7^15.1 × 9^15.1 = (63)^?
=> (63)^15.1 = (63)^?
=>? = 15.1

Option E
√33124 * √2601 – (83)^2 = (?)^2 + (37) ^ 2
=>182 * 51 – 6889 = (x)^2 + (37) ^ 2
=> 9282 – 6889 = (x)^2 + (37) ^ 2
=> 2393 = (x)^2 + (37) ^ 2
=> 2393 =(x)^2 +1369
=>1024 =(x)^2
=> x=√1024
=>x=32

305.75
300.00
Option D
5(17/37) × 4(51/52) × 11(1/7) + 2(3/4) = ?
= 202/37 × 259/52 × 78/7 + 11/4 = ? = (202 × 7)/52 × 78/7 + 11/4
=> ? = (101 × 6)/2 + 11/4
=> ? = (1212 + 11)/4
= 1223/4 = 305.75
