Question

So, 10 3/1000 3/19.683 = 2.7. Hence, EXERCISE-4.2 Find the cube root Show that: (c) 79507
​

Answer 1

Answer:

We know the corollary: if a+b+c=0 then a3+b3+c3=3abc

Using the above corollary taking a=−10, b=3 and c=7, we have a+b+c=−10+3+7=0 then the value of (−10)3+(3)3+(7)3 is:

(−10)3+(3)3+(7)3=3(−10×3×7)=−630

Hence, (−10)3+(3)3+(7)3=−630
