What is (2√10)²? You could think about this in two different ways: (2√10)² = (2√10)(2√10) {multiplied by itself} = 4√100 {multiplied} = 4(10) {evaluated square root of 100} = 40 {multiplied} Could have also done this: (2√10)² = 2² (√10)² {squared each item in parentheses} = 4(10) {evaluated exponents} = 40 {multiplied} © Algebra House
