Let's break these down. a) To find the 4th roots of 81: Step 1: We are looking for a number x such that x^4 = 81. Step 2: We know that 3 × 3 × 3 × 3 = 81. So, 3^4 = 81. Step 3: We also know that (-3) × (-3) × (-3) × (-3) = 81. So, (-3)^4 = 81. Step 4: Therefore, the 4th roots of 81 are 3 and -3. The 4th roots of 81 are 3 and -3. b) To find the cube root of 125: Step 1: We are looking for a number y such that y^3 = 125. Step 2: We know that 5 × 5 × 5 = 125. So, 5^3 = 125. Step 3: Therefore, the cube root of 125 is 5. The cube root of 125 is 5. Last free one today — make it count tomorrow, or type /upgrade for unlimited.
