How do you find the value of √a⁴ ??
(ill give brainliest)

△cde maps to △stu with the transformations (x, y) arrowright (x − 2, y − 2) arrowright (3x, 3y) arrowright (x, −y). if cd = a + 1, de = 2a − 1, st = 2b + 3 and tu = b + 6, find the values of a and b. the value of a is and the value of b is .

Hi my sisters and brothers can tell me the answer because i don’t understand the question
