<span>This is a tricky question that Reina and Sam are multiplying (84)5 (73)9
and their work are
</span><span>(84)5 (73)9 = 84 + 573 + 9 = 89712 Reina's
(84)5 (73)9 = 84⋅573⋅9 = 820727 Sam's
Actually they are doing or multiplying using exponents.
</span>
Reina’s work
(8⁴)₅(7³)⁹=8⁴⁺⁵+ 7³⁺⁹= 8⁹ 7¹²<span>
This is incorrect because she added exponents
instead of multiplying exponents
Sams work (8</span>⁴<span>)</span>⁵<span> (7</span>³<span>)</span>⁹<span>=8</span>⁴ˣ⁵<span> 7</span>³ˣ⁹<span>= 8</span>²⁰<span> 7</span>²⁷<span>
<span>This is correct because Sam multiplied exponents correctly</span></span>
<span><span>Exponents are multiplied not added.</span></span>
<em><u>x>23 is the correct answer.</u></em> First you had to subtract by 3 from both sides of equation. And it gave us, 
. Then simplify, and it gave us, 
. Next, multiply by 2 from both sides of equation, and it gave us, 
. Then simplify, and it gave us, 
. You can also subtract by 3 from both sides of equation, and it gave us, 
. Then simplify, and it gave us, 
. Multiply by -1 from both sides of equation, and it gave us, 
. Finally simplify, and it gave us the answer is<u><em> x>23 is the right answer. </em></u>Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
