My favorite season of the year is spring. The weather in spring is mild and comfortable, with the occasional refreshing rain showers. The trees bloom with colorful flowers, and the leaves return to the branches. I love spending time outdoors during spring, taking walks in nature and enjoying the blossoms. Spring brings a sense of renewal and new beginnings, making it a joyful and inspiring season for me.

\(3^8\cdot2^7\)

\(=3^7\cdot2^7\cdot3\)

\(=\left(3\cdot2\right)^7\cdot3=6^7\cdot3\)

\(=839808\)

\(3^8\times2^7=3^7\times3\times2^7=\left(3\times2\right)^7\times3=6^7\times3\)

Tim xy giup nhe

\(\left(x-3\right)\left(y+2\right)=7\)

=> \(x-3;y+2\) là ước của 7

Ta có bảng sau:

x-3

y+2

7

-7

Vậy ta có 4 cặp số x,y thoả mãn đề bài là (4,5);(10,-1);(2,-9);(-4,-3)

\(x+\dfrac{1}{3}=-\dfrac{1}{5}-2x\)

\(x=-\dfrac{1}{5}-\dfrac{1}{3}-2x\)

\(x=-\dfrac{8}{15}-2x\)

\(\Rightarrow3x=-\dfrac{8}{15}\)

\(\Rightarrow x=-\dfrac{8}{15}\cdot\dfrac{1}{3}=\dfrac{-8}{45}\)

7 tháng 7 2023

\(x+\dfrac{1}{3}=-\dfrac{1}{5}-2x\)

\(x+\dfrac{1}{3}+\dfrac{1}{5}+2x=0\)

\(3x+\dfrac{8}{15}=0\)

\(3x=0-\dfrac{8}{15}\)

\(3x=-\dfrac{8}{15}\)

\(x=-\dfrac{8}{45}\)

 Vì \(\left(8\times x-16\right)\times\left(x-5\right)=0\)

=> \(8\times x-16=0\) hoặc \(x-5=0\) 

TH1:

\(8\times x-16=0\) 

        \(8\times x=16\) 

               \(x=16\div8\) 

                \(x=2\) 

TH2:

         \(x-5=0\) 

                 \(x=5\) 

           Vậy \(x\in\left\{2;5\right\}\)

Gọi tập hợp các số chính phương là A

Mà \(90< A< 200\)
