Answer:

(3\sqrt[5]{5} )^{x}

Step-by-step explanation:

Given that

\sqrt[5]{1215^{x} }

=> 1215^{\frac{x}{5} } Using radical rule

=> (3*3*3*3*3*5)^{\frac{x}{5} }

=> (3^{5} * 5 )^{\frac{x}{5} }

=> (3^{5*\frac{1}{5} } * 5 )^{x}

=> (3*5^{\frac{1}{5} } )^{x}

=> (3\sqrt[5]{5} )^{x}

Answer:

5\sqrt{1215^{x}}\Rightarrow 45\sqrt{15^{x}}\:\:or\:\:45*15^{\frac{x}{2}}

Step-by-step explanation:

1) Performing Prime Factorization

\\1215|3\\405|3\\135|3\\45|3\\15|3\\5|5\\1\Rightarrow 3^{2}*3^{3}*5

2) Simplifying

5\sqrt{3^{2}*3^{2}*3*5}\Rightarrow 5*9\sqrt{15^{x}}\Rightarrow 45\sqrt{15^{x}}

3) Rewriting it as a power, where the denominator is the index, and the numerator is the exponent:

45\sqrt{15^{x}}\:\:=\:\:45*15^{\frac{x}{2}}

adell [148]

Answer:

its c. x = -2.5 and x = -2

Step-by-step explanation:

multiply function (g)(x) = (-2x-5)(x-2)

= -2x^2+4x-5x+10

first get out -2x(x+2)-5(x+2)

(-2x-5) or (x+2) = 0

x=-5/2 or x=-2

its c that both points covered in that line of x axis
