Which sequences of transformations applied to shape 1 prove that shape 1 is similar to shape 2

A.  reflection across the x-axis, followed by a reflection across the y-axis, and then a dilation by a scale factor of 0.5

2/1 or just 2. sorry if i get this wrong

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.
