Question

cube root of 1+3+5+7.....+53 please explain

Answer 1

Answer:

328509

Step-by-step explanation:

1+3+5+7+53=69

69^3=328509

Answer 2

First we need number of terms in the series.

It is an arithmetic progression.

First term =1 . Common difference =2.

1 + (n-1) * 2 = 53.

》 2*(n-1) = 52.

》 n = 27.

Sum of natural odd number series

= n ^ 2

= 27^2.

Cube root = (27^2) ^(1/3)

=3 ^ ( 3 * 2 * 1/3 )

=3^2

=9.
