Step-by-step explanation:
Q-4:-
I)
Given that. √[5³×7³×35]
=> √[5×5×5×7×7×7×5×7]
=> √[(5×5)(5×5)(7×7)(7×7)]
=> 5×5×7×7
=> 1225
Or
Given that √[5³×7³×35]
=> √(5³×7³×5×7)
=> √[(5³×5)×(7³×7)]
=> √(5⁴×7⁴)
=> √(5×7)⁴
=> √(35)⁴
=> √[(35²)²]
=> 35²
=> 35×35
=> 1225
II) Given that √(2.25/12.25)
=> √[225/100)/(1225/100)]
=> √(225/1225)
=> √(15²/35²)
=> √(15/35)²
=> 15/35
=> 3/7 (or) 0.428..= 0.43 (approximately)
Or
Given that √(2.25/12.25)
=> √[225/100)/(1225/100)]
=> √(225/1225)
=> √[(9×25)/(49×25)]
=> √(9/49)
=> √(3²/7²)
=> √(3/7)²
=> 3/7 (or) 0.428..= 0.43 (approximately)
Answer:-
I) √[5³×7³×35] = 1225
II) √(2.25/12.25) = 3/7 (or) = 0.43
Used formulae:-
→ a^m × a^n = a^(m+n)
→ (a/b)^m = a^m / b^m
→ √a² = a
