A blue number cube and a green number cube are rolled. Both number cubes have the numbers 1 through 6 on them.
What is the probability of rolling a number greater than 3 on
the blue cube and a number less than 4 on the green cube?

Not sure what the question is?

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.
