(i) 30.232342345...
(vi) 0.3030030003...

Answer 1

Step-by-step explanation:

Rational number

√441 = √21² = 21 = 21/1

7.484848....... = 741/99 ( non terminating repeating decimal)

30.232342345 = 30232342345/1000000000 terminating decimal

11.2132435465 = 112132435465/10000000000 ( terminating Decimal)

Irrational numbers are non terminating non repeating decimals

or surd of non perfect squares

Irrational numbers

√27 = 3√3 - Surd

0.3030030003..... non terminating non repeating decimal
