<h3><u>Explanation</u></h3>
  • Properties of Exponent

{a}^{ \frac{m}{n} }  =  \sqrt[n]{ {a}^{m} }

  • Convert the expressions from radical to exponent form.

9 \sqrt[4]{ {t}^{3} }  \times 7 \sqrt[3]{ {t}^{2} }  \\ 9( {t}^{ \frac{3}{4} } ) \times 7( {t}^{ \frac{2}{3} } )

  • Simplify the expression by multiplying.

63( {t}^{ \frac{3}{4} }  \times  {t}^{ \frac{2}{3} } )  = 63( {t}^{ \frac{3}{4}+\frac{2}{3} } ) \\ 63( {t}^{ \frac{9}{12} + \frac{8}{12} } ) \\ 63( {t}^{ \frac{17}{12} } )Answer[tex] \large \boxed {63 {t}^{ \frac{17}{12} } }

What is the vertex of the parabola whose equation is y = (x + 1) ^2+ 3
lora16 [44]

Answer:

The vertex is (-1, 3)

Step-by-step explanation:

The form this is in is called vertex form. We can express the equation using its base form.

y = a(x - h)^2 + k

Now we can identify the vertex as (h, k). By looking at the equation, we can see h is equal to -1 and k is equal to 3.
