Question

simplify night Standard form 2^5×7^3 / 8^3×7​

Answer 1

Answer:

$\frac{ {2}^{5} \times {7}^{3} }{ {8}^{3} \times 7} = \frac{ {2}^{5} \times {7}^{3} }{ {2}^{(3 \times 3)} \times 7 } \\ = \frac{ {2}^{5} \times {7}^{3} }{ {2}^{9} \times 7 } \\ = \frac{ {7}^{2} }{ {2}^{4} } \\ = \boxed{\frac{49}{16} }$

49/16 is the right answer.
