Explanation:
1. ?% of 200÷√2401×2 = (46% of 750+√256-√324) ÷?% of 16807
?×2÷49×2 = (345+16-18) ÷?% of 16807
?×2÷49×2 = 343 ÷?% of 16807
?×2×?% of 16807×2= 343×49
?×? = 343×49÷16807×100÷2÷2
?×? = 25
? = 5
2. √1156÷221×√289 – 114+204×3÷2 = ?+146.61
34÷221×17 - 114+306 = ?+146.61
2.61+192 = ?+146.61
2.61+192-146.61= ?
? = 48
3. ?×√961÷√784 = ∛1728×2×93×√49÷?÷√64?×31÷28 = 12×2×93×7÷?÷8
?×?= 12×2×93×7÷8÷31×28
3. ?×√961÷√784 = ∛1728×2×93×√49÷?÷√64?×31÷28 = 12×2×93×7÷?÷8
?×?= 12×2×93×7÷8÷31×28
?×? = 1764
? = 42
4. ?% of 350+20×1.5-33 = 32
?×3.5+30-33 = 32
?×3.5 = 32+3
?×3.5 = 35
? = 10
