Answer» a)the units digit of (36)^2 will be units digit of (6*6)= 6so (a)-->(iv) b) 300*300=90000so number of zeros is 4b)--->(v) c)5^2=25 and 6^2= 36all numbers between 25 and 36 are non perfect squares. there are 10 numbers.(c)--->(ii) d) here, let one number be x and lets take 3 consecutive odd natural numbers.so x+x+2+x+4=64will give a decimal value for xnow we take 4 consecutive odd natural numbers:x+x+2+x+4+x+6=64this will give the value of x as 13so we need 4 consecutive odd natural numbers.d)--->(v) e) no of digits is 3 for example: square root of 15625 is 125e)--->(vi) f) square root of 625 is 25f)---> (iii) |
