Jamal simplified the expression StartRoot 75 x Superscript 5 Baseline y Superscript 8 Baseline EndRoot where x greater-than-or-equal-to 0 and y greater-than-or-equal-to 0. StartRoot 75 x Superscript 5 Baseline y Superscript 8 Baseline EndRoot = StartRoot 25 times 3 times x Superscript 4 Baseline times x times y Superscript 8 Baseline EndRoot = 5 x squared y squared StartRoot 3 x EndRoot Which describes the error Jamal made? He should have written the square root of y Superscript 8 in the answer as y Superscript 4, not y squared. He should have written the square root of x Superscript 4 in the answer as x, not x squared. He should have written the 5 inside of the radical in the answer. He should have written the 3 outside of the radical in the
