Question

How do you simplify `(-16a^2bc^4)/(8ab^2c^4)`?

Answer 1

#(2a)/b

Explanation:

You have to subtract the exponent of each variable/number in denominator from the exponent in the numerator...
`-(2^4*a^2*b^1*c^4)/(2^3*a^1*b^2*c^4)`
-`2^(4-3)*a^(2-1)*b^(1-2)*c^(4-4)`
-`2^1*a^1*b^-1*c^0` Simplify
`(2a)/b`
