Which expression is equivalent to
(20a^2b^0c^-4)(3a^15b^12c^0)
To find the equivalent expression, we need to multiply the coefficients together and add the exponents with the same base.
(20a^2b^0c^-4)(3a^15b^12c^0)
Multiplying the coefficients 20 and 3, we get 60.
The exponent of a is 2 + 15 = 17.
The exponent of b is 0 + 12 = 12.
The exponent of c is -4 + 0 = -4.
Therefore, the equivalent expression is 60a^17b^12c^-4.
