Define the value of the expression 3^2 x 3^{-5}
Tanya [424]

Answer:

Between 0 and 1

Step-by-step explanation:

The given expresion is

{3}^{2} \times  {3}^{ - 5}

Recall that:

{a}^{m}  \times  {a}^{n}  =  {a}^{m + n}

We apply this property of exponents to get;

{3}^{2}  \times  {3}^{ - 5}  =  {3}^{2 +  - 5}  =  {3}^{ - 3}

We rewrite to obtain a positive index as:

{3}^{2}  \times  {3}^{ - 5}  =  \frac{1}{ {3}^{3} }  =  \frac{1}{27}

Therefore the value of the expression is between 0 and 1.

Brian correctly use a method of completing the square to solve the equation X a 2nd plus 7X -11 equals zero Brian‘s first step w
ArbitrLikvidat [17]

Answer:

(\frac{7}{2})^{2}

Step-by-step explanation:

Brain correctly use a method of completing the square to solve the equation:

x^2+7x-11=0

His First Step is to: Take the Constant Term to the Right Hand Side

x^2+7x=11

The Next Step Would be to:

  • Divide the Coefficient of x by 2
  • Square It
  • Add it to both Sides

In this case, the Coefficient of x  = 7

  • Divided by 2 = \frac{7}{2}
  • Squaring It, we have: (\frac{7}{2})^{2}

It is this number (\frac{7}{2})^{2} that is added to both sides in the manner below:

x^2+7x+(\frac{7}{2})^{2}=11+(\frac{7}{2})^{2}
