According to exponent rules, when we multiply the coefficients we _______ the exponents.

• add
• subtract
• multiply
• divide

Explain the error in the simplification below:
x³yx^-4z^-2=x^-1yz^-2

• Should have multiplied the x exponents.
• Should have subtracted the x exponents.
• Should have moved the negative exponents to the bottom of a fraction.
• There is no error.
