{3}^{4}  \times  {3}^{ - 9}  =  {3}^{4}  \times (1/ {3}^{9}) =  {3}^{4} \div  {3}^{9}  \\  {3}^{(4 - 9)}  =  {3}^{ - 5}  = 1/( {3}^{5} )
So the 2nd answer is correct: 1 / 3^5

COMPLETE THE SQUARE TO REWRITE Y=X&gt;2+8X+3 IN VERTEX FORM , AND THEN IDENTIFY THE MINIMUN Y-VALUE OF THE FUNCTION
kicyunya [14]

Answer:

The vertex form is y = (x + 4)² - 13

The minimum value of the function is -13

Step-by-step explanation:

∵ y = x² + 8x + 3

∵ 8x ÷ 2 = 4x ⇒ (x) × (4)

∴ We need ⇒ x² + 8x + 16 to be completed square

∴ y = (x² + 8x + 16) - 16 + 3 ⇒ we add 16 and subtract 16

∴ y = (x + 4)² - 13 ⇒ vertex form

∵ The vertex form is (x - a)² + b

Where a is the x-coordinate of the minimum point and b is y-coordinate of the minimum point (b is the minimum value of the function)

∴ The minimum value is -13
