Assume that 3+2 root 3 is rational. 3+2 root 3=a/b (3-a)/b=2 root 3 (3b-a)/b=2 root 3 (3b-a)/2b=root 3 Therefore our assumption is wrong,(3b-a)/2b is a rational number which implies that root 3 is irrational. Therefore,3+2 root 3 is irrational.

Let 3+√3 is a rational no. So it is in the form of p/b where q≠0 P/b=3+√3 => p/b-3=√3 LHS is a rational no, so RHS should be rational, But we know that √3 is irrational. This contradicts to the fact that 3+√3 is rational. Hence 3+√3 is irrational.

Bile does not contain any enzyme but it is essential for digestion. why?

Posted by Shibu Varghese 4 years, 9 months ago

CBSE > Class 10 > Science

2 answers

Adithya Dev A 4 years, 9 months ago

There are two reasons behind why Bile is important for digestion of fats though it lacks an enzyme. 1) It breaks down large fat globules into smaller fat droplets causing the emulsification of fats so that a greater surface area is available for faster action of lipase. 2) It provides an alkaline medium for activating lipase.

Bile juice is Important because:- * It emulsifies the fat * It convert big fat globules into small one

Divya Soni 4 years, 9 months ago

Grouping lets you rotate, flip, move, or resize all shapes or objects at the same time as though they were a single shape or object. You can also change the attributes of all of the shapes in a group at one time, such as adding a shape fill or effect, or an effect to a picture.

By grouping objects, we can apply any effects on the object at the same time. We don't need to select objects one by one and apply the same effect like colour,shadow.
