Which expressions are equivalent to 1/5 • 1/5 • 1/5 • 1/5

1/625

Step-by-step explanation:

The dots between the fractions mean multiply. Multiply all the numerators together, then all the denominators.

     1x1x1x1 = 1

5×5×5×5 = 625

If you put it in a calculator, you get 0.0016

or as an exponential expression  or  

Negative exponents mean "the reciprocal of the base to the power"

in this case, 5^4 is and that's 625. the reciprocal is 1/625.

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
