Question

Express 64 as the sum of 8 odd numbers

Answer 1

Answer:

Step-by-step explanation:

Suppose x is a odd no.;

So sum of 8 odd no.  = 64;

x + x+2+x+4+x+6+x+8+x+10+x+12+x+14 = 64;

8x +56 = 64;

8x = 64-56;

8x = 8;

x = 1;

So odd numbers are = 1,3,5,7,9,11,13,15,17 and there sum is 64

Answer 2

Answer:

sum of 8 odd numbers :

1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64

Step-by-step explanation:

Let the odd number is x

According to the given question :

x + x+2 + x+4 + x+6 + x+8 + x+10 + x+12 +x+14 =64

8x + 56 = 64

8x = 64-56

8x = 8

x = 1

Hence, odd numbers are :

x + x+2 + x+4 + x+6 + x+8 + x+10 + x+12 +x+14 =64

1 + (1+2) + (1+4) + (1+6) (1+8) + (1+10) + (1+12) + (1+14) =64

1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64
