Which is equivalent to x^3 y^-7

PilotLPTM [1.2K]

For this case we must find an expression equivalent to:

$x ^ 3 * y ^ {- 7}$

By definition of power properties we have to meet:

$a ^ {-1} = \frac {1} {a ^ 1} = \frac {1} {a}$

Then, we can rewrite the expression as:

$x ^ 3 * \frac {1} {y ^ 7} =\\\frac {x ^ 3} {y ^ 7}$

Answer:

$\frac {x ^ 3} {y ^ 7}$

What are the zeros of this polynomial and state their multiplicity at each y=(x-5)(x+2)^2

N76 [4]

Answer:

Step-by-step explanation:

The zeros of a polynomial are the x-intercepts of the function. To find them, we factor the polynomial and set each factor equal to 0.

This polynomial is already factored so set each to 0 and solve for x.

$x-5=0\\x=5\\(x+2)^{2}=0 \\(x+2)=0\\x=-2$

This means x=-2, 5. Each zero or root has a multiplicity - the number of times the factor occurs. This is also known as the exponent of the factor expression.

(x+5) occurs once since it has exponent 1.

$(x+2)^{2}$ occurs twoce since it has exponent 2.

x=5 mult. 1, x=-2 mult. 2
