What is a a? 72 90 80 120 Submit Show explanation View wiki WebbYes, you can take that approach. But, your work is incomplete. When you simplify a square root, you need to ensure you have removed all perfect squares. With 3√8, you still have a perfect square inside the radical. 3√8 = 3√(4*2) = 3√4 * √2 = 3*2√2 = 6√2 Hope this helps.

Webb16 nov. 2024 · We are going to be simplifying radicals shortly so we should next define simplified radical form. A radical is said to be in simplified radical form ... is larger than the index (2) and so the first rule for simplification is violated. To fix this we will use the first and second properties of radicals above. Webb22 dec. 2024 · By Grace Williams. A radical, or root, is the mathematical opposite of an exponent, in the same sense that addition is the opposite of subtraction. The smallest radical is the square root, represented with the symbol √. The next radical is the cube root, represented by the symbol ³√. The small number in front of the radical is its index ... Webb17 apr. 2016 · To denest, you have to assume that the radical can be rewritten as the sum of two other radicals (surds). So we have 24 + 8 5 = x + y Squaring both sides gives us 24 + 8 5 = x + y + 2 x y So we have x + y = 24 and 2 x y = 8 5. So x ⋅ y = 80. This can be easily solved by finding two numbers whose sum is 24 and their product is 80. open chrome browser menu
