Question

find the rationalizing factor of the following:
1. √48
2. 7/4√32​

Answer 1

Answer:

1. 2*2*√3=4√3

2. 7/4*4*√2=7√2

Step-by-step explanation:

Answer 2

Answer:

the factor of multiplication by which rationalisation is done,

rationalizing factor for √48 is simple √48 so √48*√48 = 48

in this process we just rationalize the irrational number...

7/4 √32 --------------------(1)

how could we rationalize this number by multiplying which number?

let's take the number within the roots for convenience,

we can simplify this √32 further into √16*√2

then , becomes 4*√2

from eqn 1,

=7/4 (4*√2)

= 7(√2)

in order to rationalize we multiplied the √2 with above eqn

7* {√2*√2}

7*2 = 14 which is the required answer...

answers

1) 48

2) 14
