20 points an brainliest which pair do both decimals represent rational numbers?

Step-by-step explanation:

There are 3 types of decimals you can find:

Terminating decimals are rational and have a finite number of digits after the decimal point (0.296, 0.34)Repeating decimals are also rational and have a repeating infinite number of digits after the decimal point (0.9888..., 0.5555...)Non-terminating and non-repeating decimals are irrational

Hence the correct answer is option C.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
