Irrational Numbers are numbers that cannot be expressed as a ratio. They are long decimals that never end and do not repeat. For number 1: A) Circle -6.123638... B) Circle -4π C) Circle √10 /2 D) Circle 3.1415 For number 3: A) To get rid of the exponent 2, you square root both sides and you get x= 12 B) 4*4*4 equals 64. x=4 Hope this helps!
