Question

calculhe o conciente
(2/7a^4x³):(4/7ax²)

Answer 1

( 2/7)a⁴ x³ / ( 4/7) a¹ x²
2/7 : 4/7  = 2/7 * 7/4 = 14/28 = 1/2 ***
a⁴ : a¹  = a⁴⁻¹  = a³
x³: x² = x³⁻² = x¹
resposta  1/2a³x ou  ( a³x)/2 ****

Answer 2

.
$( \frac{2}{7} a^4x^3)\div( \frac{4}{7} ax^2)= \\ \\ \frac{\not2}{\not7} . \frac{\not7}{\not4_2} a^{4-1}.x^{3-2}= \\ \\ \frac{1}{2} a^3.x~~~~ou~~~~2^{-1}a^3x$
