The irrational numbers are numbers that cannot be written as a fraction of two integers.
Out of the given options, 2√3 is irrational because it involves the square root (√) of a non-perfect square.
So, the answer is 2√3.
Out of the given options, 2√3 is irrational because it involves the square root (√) of a non-perfect square.
So, the answer is 2√3.

I apologize for the error in my previous response.
Upon reviewing the options again, the correct answer is 0.343434..., which is a recurring decimal. Recurring decimals cannot be expressed as a fraction, therefore it is an irrational number.
So, the answer is 0.343434...

To determine which of the following is an irrational number, we need to identify the options that cannot be written as a fraction or a terminating decimal.
Based on the options provided:
-1529 is an integer and can be written as the fraction -1529/1, so it is a rational number.
0.343434... is a repeating decimal and cannot be expressed as a fraction or a terminating decimal, so it is an irrational number.
2√3 involves the square root (√) of a non-perfect square (3), so it is also an irrational number.
87.9821 is a terminating decimal and can be expressed as a fraction (879821/10000), so it is a rational number.
So, the options that are irrational numbers are 0.343434... and 2√3.
