Question

simplify (3power 8÷3power 5)×3power -3

Answer 1

this is the answer for the question

Answer 2

$\frac{ {3}^{8} }{ {3}^{5} } \times {3}^{ - 3}$

As
$\frac{ {x}^{y} }{ {x}^{z} } \: \: then \: {x}^{(y - z)}$

By using this,

you'll get

${3}^{(8 - 5)} \times {3}^{ - 3} \\ = {3}^{3} \times {3}^{ - 3}$

and as
${x}^{y} \times {x}^{z} = {x}^{(y + z)}$

using this, you'll get
${3}^{(3 +( - 3))} \\ = {3}^{(3 -3)} \\ = {3}^{0} \\ = 1 \\ \\ \: as \\ {x}^{0} = 1$
