Question

state with reason if it's a surd

$\sqrt[4]{250 } \sqrt[4]{40}$
​

Answer 1

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Answer 2

Step-by-step explanation:

$\huge \pink { a} \fbox \green {n} \fbox \red {s} \fbox \blue {w} \fbox \orange { e} \fbox \purple { r}$

The order of a surd indicates the index of root to be extracted.

In√ n

a

, n is called the order of the surd and a is called the radicand.

For example: The order of the surd √5

is 5.

(i) A surd with index of root 2 is called a second order surd or quadratic surd.

The surds which have the indices of root 2 are called as second order surds or quadratic surds. For example√2, √3, √5, √7, √x are the surds of order 2.

Example: √2, √5, √10, √a, √m, √x, √(x + 1) are second order surd or quadratic surd (since the indices of roots are 2).
