Explanation

15 men complete the work in 8 days

Total work = 15 men * 8 days = 120 man-days

Now, to complete the work in 10 days:

120 man-days / 10 days = 12 men

Explanation

Percentage of games won = (Games won / Total games) * 100

= (18 / 30) * 100

= 0.6 * 100

= 60%

Explanation

To find the compound ratio, multiply the corresponding parts:

(3 * 8 * 25) : (4 * 15 * 28)

= 600 : 1680

Simplifying the ratio:

= 600 / 1680 = 5/14

= 5 : 14

Explanation

Given that x added to itself 13 times gives 112:

x + 13x = 112

14x = 112

x = 112 / 14

x = 8

Explanation

Given:

(1+x)(1+x2)(1+x4)(1+x8)(1−x),

$$$$(1+x)(1+x2)(1+x4)(1+x8)(1−x)

This is a well-known identity in algebra that builds up as a geometric progression product:

Identity:

(1−x)(1+x)(1+x^2)(1+x^4)(1+x^8)=1−x^16

$$$$(1−x)(1+x)(1+x2)(1+x4)(1+x8)=1−x16

So,

(1+x)(1+x^2)(1+x^4)(1+x^8)(1−x)=1−x^16

$$$$(1+x)(1+x2)(1+x4)(1+x8)(1−x)=1−x16
