Plz solve this all parts​

Answer 1

Answer:

firstly factorise the all no.s

a.) -9261

these all are the factorise = 3 * 3 * 3 * 7 * 7 * 7

to find cube we no. as common if it is of 3 pairs

= 3 * 7

= 21

now you can put minus sign

= -21

______________________________________

same to with all

- 8000

= 2 * 2* 2*2*2*2*5*5*5

= 2*2*5

= 20

now put minus = - 20

__________________________________

-5832

= 2*2*2*3*3*3*3*3*3

= 2*3*3

= 18

now put minus = -18

___________________________________

- 32768

= 2*2*2*2*2*2*2*2*2*2*2*2*2*2*2

= 2*2*2*2*2

= 32

now put minus = -32
