Question

which of the following are perfect cubes ??
a) 15625
b) 9260
c) 10648
d) 32768

Answer 1

Answer:

(a)- 15625 i think this is answer

Step-by-step explanation:

because his prime factor is

5×5×5×5×5×5 = 15625

Answer 2

Step-by-step explanation:

you can subtract by odd number and try for example

15625-1=15624 15624-3=15621 15621-5=15616

15616-7=15609 15609-9=15600 15600-11=15589 15589-13=15576 15576-15=15561 15561-17=15544

etc if you get zero till end then that means it is a perfect square

second method is that...

PRIME FACTORIZATION

I hope you understand this

2(9260

2(4630

2(2315

5(463

now 463 is not divisible also to find the perfect cube or not it will be like this also

2 (128

2 (64

2 (32

2 (16

2 (8

2 (4

2 (2

1

here 2x2x2 is 2 cause we have to find the perfect CUBE which mean 3 then 2x2x2 will be 2

then next 2x2x2 is 2 but one 2 is alone that mean 128 is not a perfect cube

I HOPE YOU UNDERSTOOD MARK ME AS THE BRAINLIEST ANSWER AND HAVE A GREAT DAY BYE
