Answer:

<h2><em><u>6</u></em><em><u>^</u></em><em><u>2</u></em></h2>

Step-by-step explanation:

<h3><u>Question</u><u>:</u><u>-</u></h3>
  • To simplify the given expression

<h3><u>Expression</u><u>:</u><u>-</u></h3>
  • \frac{ {6}^{4} .  {6}^{3}  }{ {6}^{5} }
<h3><u>Solution</u><u>:</u><u>-</u></h3>

= \frac{ {6}^{4} .  {6}^{3}  }{ {6}^{5} }

  • <em>[</em><em>As</em><em> </em><em>we</em><em> </em><em>know</em><em>,</em><em> </em><em>a</em><em>^</em><em>x</em><em> </em><em>.</em><em> </em><em>a</em><em>^</em><em>y</em><em> </em><em>=</em><em> </em><em>a</em><em>^</em><em>(</em><em>x</em><em>+</em><em>y</em><em>)</em><em>]</em>

=  \frac{ {6}^{(4 + 3)} }{ {6}^{5} }

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=  \frac{ {6}^{7} }{ {6}^{5} }

  • <em>[</em><em>As</em><em> </em><em>we</em><em> </em><em>know</em><em>,</em><em> </em><em>a</em><em>^</em><em>x</em><em> </em><em>/</em><em> </em><em>a</em><em>^</em><em>y</em><em> </em><em>=</em><em> </em><em>a</em><em>^</em><em>(</em><em>x</em><em>-</em><em>y</em><em>)</em><em>]</em>

=  {6}^{(7 - 5)}

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=  {6}^{2} (ans)

\bf\huge Question:—

\bf \: 6^4.6^3 \: over \:  {6}^{5}

\bf\huge Solution:—

\sf\longmapsto \: \dfrac{6^4.6^3}{ {6}^{5} }

\boxed{\bf \: Note \:  that  \: '.'  \: sign = \times}

\sf\longmapsto \dfrac{6^4 \times 6^3}{ {6}^{5} }

\sf\longmapsto \:  \dfrac{ \cancel6^4 \times 6^3}{  \cancel{6}^{5} }

\boxed{\bf \: Cancel\: 6^4\: and \:6^5 , ans\:  is\: 6^1.}

\sf\longmapsto \:  \dfrac{ {6}^{3} }{ {6}^{1} }

\boxed{\bf \: Simply\: subtract\: 3-1 \: as \: \: a^n/a^n \:  = \: a^{n-n} \: .}

\sf\longmapsto \: 6 {}^{3 - 1}

\sf\longmapsto6 {}^{2}

________________________________

\boxed{\bf Solving\: In \: Another \: Way}

\sf\longmapsto \dfrac{1296( {6}^{3} )}{6 {}^{5} }

\sf\longmapsto \:  \dfrac{1296(216)}{ {6}^{5} }

\sf\longmapsto \:  \dfrac{279936}{ {6}^{5} }

\sf\longmapsto \:  \dfrac{279936}{7776}

\sf\longmapsto \: \cancel \dfrac{279936}{7776}

\sf\longmapsto36

\boxed{\bf Now \:Convert \:36\: to \:exponent}

\sf\longmapsto 36

\sf\longmapsto 6^2(6×6)

\sf\longmapsto  {6}^{2}

________________________________

\boxed{ \bf \: Answer \:  is \:  Option \:  A }

\boxed{  \bf \:  {6}^{2} }

Graph the system of equations. <br> {<br> 8x+8y=64<br> 2x−2y=−4
siniylev [52]

What you do is you rearrange and simplify both equations to have them in terms of y, and then graph them. If it asked for a solution, their point of intersection would be the solution.
