Use the properties of integer exponents to simplify the expression (3y)^0.(1 point)
The property of any number, except zero, raised to the power of zero is equal to 1. Therefore, the expression (3y)^0 simplifies to 1.

−18b^11
To simplify the expression (-3b^4)(6b^7), you can multiply the coefficients (-3)(6) to get -18, and then add the exponents of the same base b, so b^4 * b^7 = b^(4+7) = b^11.
Therefore, the simplified expression is -18b^11.
Apply the properties of integer exponents to generate an equivalent algebraic expression to (−2x−3)04x0
.(1 point)
To generate an equivalent algebraic expression for (-2x^-3)^0(4x^0), we can use the property that any non-zero number raised to the power of 0 is equal to 1.
Therefore, the equivalent algebraic expression is 1.
Apply the properties of integer exponents to generate an equivalent algebraic expression to (−2x^−3)^0/4x^0
.(1 point)
To generate an equivalent algebraic expression for (-2x^-3)^0 / (4x^0), we can use the property that any non-zero number raised to the power of 0 is equal to 1. Additionally, any number divided by 1 remains unchanged.
Therefore, the equivalent algebraic expression is 1 / (4x^0), which simplifies to 1/4.

To simplify the expression −25x^8 * 5x, we can multiply the coefficients -25 * 5 to get -125. Then, we can combine the variables with the same base by adding their exponents, which gives us x^8 * x^1 = x^(8+1) = x^9.
Therefore, the simplified expression is -125x^9.

To simplify the expression −25x^8 / 5x, we can divide the coefficients -25 / 5 to get -5. Then, we can subtract the exponents of the same base by subtracting 8 - 1 = 7.
Therefore, the simplified expression is -5x^7.
