HELLO. GOOD AFTERNOON GUYS PLZ CAN SOME SOLVE THE 5 AND 2 QUESTION FOR ME☺✌✌✌WHO EVER DOES THNKS A LOT ✌✌☺

Answer 1

Hey Friend ☺

Q.1

( i ) 8root3 , 2root15 , 2root6, 11 , 3root7

8root3 = root64 × 3

= root192

2root15 = root15 × 4

= root60

2root6 = root 6 × 4

= root24

11 = root121

3root7 = root 9 × 7

= root63

Now compare the numbers which are inside the root .

They are 192 , 60 , 24 , 121 , 63

Ascending order => 24 , 60 , 63 , 121 , 192

So ascending order of surds => 2root6 , 2root15 , 3root7 , 11 , 8root3

Q.2

Let the number be x

So we get equation,

1/26 ÷ x = -8/39

》1/26 × 1/x = -8/39

》1/x = - 8/39 × 26

》1/x = - 8/3 × 2

》1/x = - 16/3

》x = -16/3

Hope it helps you ..!!
