The properties of exponents state that when dividing monomial bases with the same base, you subtract the exponents. In this case, we have -25x^8 divided by 5x.
So, -25x^8 / 5x can be simplified as:
(-25/5) * (x^8/x)
This simplifies to:
-5 * x^(8-1)
Which further simplifies to:
-5 * x^7
Therefore, the simplified expression is -5x^7.

To simplify the expression (−4a^4)(−2a^2), we can use the property of multiplying monomials with the same base. According to this property, when multiplying monomials with the same base, you add the exponents.
In this case, we have (-4a^4)(-2a^2).
As per the property, we can multiply the coefficients and add the exponents of the variables:
(-4) * (-2) * a^(4+2)
Simplifying further:
8 * a^6
Therefore, the simplified expression is 8a^6.

To generate an equivalent algebraic expression to 3x^3y^−4 / 12x^7y^4, we can apply the properties of integer exponents.
According to the properties of exponents, when dividing monomials with the same bases, you subtract the exponents. In this case, the bases are x and y.
So, we have:
3x^3y^(-4) / 12x^7y^4
To simplify the expression, we can subtract the exponents of x and y:
(3/12) * (x^(3-7)) * (y^(-4-4))
Simplifying further:
1/4 * x^(-4) * y^(-8)
Remember that negative exponents indicate the reciprocal of the base raised to the positive exponent. Therefore, x^(-4) is equivalent to 1/x^4, and y^(-8) is equivalent to 1/y^8.
Substituting these into the expression:
1/4 * 1/x^4 * 1/y^8
Combining the reciprocals:
1 / 4x^4y^8
Therefore, the equivalent algebraic expression is 1 / 4x^4y^8.
