Question

The simplest rationalising factor of ³√25+(1/cube root of 25 )-1

Answer 1

Given:

³√25+(1/cube root of 25 )-1

To find:

The simplest rationalising factor of ³√25+(1/cube root of 25 )-1

Solution:

Rationalising Factor: A factor which when multiplied by the given number results in a rational number is called the rationalising factor.

From given, we have,

³√25

we use the formula ³√a × ³√b = ³√ab

³√25 × ³√5 = ³√5³ = 5^{3/3} = 5

The simplest rationalising factor of ³√25 is ³√5

Therefore, 5 is the simplest rationalising factor
