Question

write the cube root of the following number by prime factorisation method (I) -2744/4096 ( vi) -5. 104/125​

Answer 1

Answer:

(I) -7 / 8

Step-by-step explanation:

(I) - ³√ 2744

= - ³√ 2×2×2 × 7×7×7

= - 2 × 7

= - 14

³√ 4096

= ³√ 2×2×2 × 2×2×2 × 2×2×2 × 2×2×2

= 2 × 2 × 2 × 2

= 16

Now ,

³√ ( -2744 / 4096 )

= -14 / 16

= -7 / 8
