Question

SIMPLIFIQUE:
a- (2³+¹ x 2³+³) / (2³+² x 2³)=

Answer 1

.
$( 2^4.2^6)\div(2^5.2^3)= \\ \\ (2^{4+6})\div(2^{5+3})= \\ \\ 2^{10} \div2^8= \\ \\ 2^{10-8}= \\ \\ 2^2=4$

Answer 2

(2³+¹ x 2³+³) .........2⁴ x 2⁶ ..........2¹⁰
----------------- = --------------- = -------- = 2¹⁰ : 2⁸ = 2¹⁰⁻⁸ = 2² = 4
 (2³+² x 2³) ...........2⁵ x 2³ ...........2⁸
