47+5=52

k mình, mình k lại

\(a=\frac{125.34}{85}=50\)

Vậy a=50

47+5=52

47+5=52

tk nhé

ĐKXĐ: \(x\ne3;x\ne-2\)

\(\frac{2}{x-3}=\frac{3}{x+2}\)

\(\Rightarrow2\left(x+2\right)=3\left(x-3\right)\)

\(\Rightarrow2x+4=3x-9\)

\(\Rightarrow2x-3x=-9-4\)

\(\Rightarrow-x=-13\)

\(\Rightarrow x=13\)

a,3²⁰⁰>2²⁰⁰

b,9¹²=(3²)¹²=3²⁴

26⁸=(13.2)⁸
