Question

so sánh 

a)  (-5)³⁰  và (-3)⁵⁰

Answer 1

\(\frac{a}{4}-\frac{1}{2}=\frac{3}{b}\)

tìm a,b

Answer 2

Ta có:\(-5^{30}=\left(-5^3\right)^{10}=-125^{10}\)

\(-3^{50}=\left(-3^5\right)^{10}=-243^{10}\)

=> \(-125^{10}< -243^{10}\)

=> \(-5^{30}< -3^{50}\)

Answer 3

2)(\(\frac{a}{4}-\frac{1}{2}=\frac{3}{b}\)

= \(\frac{a}{4}+\frac{\left(-2\right)}{4}=\frac{3}{b}\)

=> b = 4

=> a = 3 - (-2) = 5
