Which expression is equivalent to

(20a^{2}b^{0}c^{-4})(3a^{15}b^{12}c^{0})`

To find the expression that is equivalent to

(20a²b⁰c⁻⁴)(3a¹⁵b¹²c⁰),

we can simplify the expression by multiplying the coefficients, adding the exponents of like bases, and handling any zero exponents.

For the coefficients, we have 20 * 3 = 60.

For the variables with base "a," we add the exponents: 2 + 15 = 17.

For the variables with base "b," we add the exponents: 0 + 12 = 12.

For the variables with base "c," we add the exponents: -4 + 0 = -4.

Putting it all together, the simplified expression is:

60a¹⁷b¹²c⁻⁴.
