Học tốt !

\(3.3^2.3^3.3^4.....3^{50}\)

\(=3^{1+2+3+4+5+....+50}\)

Áp dụng công thức tính dãy số ta có

\(1+2+3+4+...+50=\frac{\left[\left(50-1\right):1+1\right].\left(50+1\right)}{2}=\frac{50.51}{2}=25.51=1275\)

\(\Rightarrow3^{1+2+3+4+...+50}=3^{1275}\)

=3^1+2+3+...+50=3¹²⁷⁵

3*^(1+2+3+4+......50)=3^(50/2*(50+1)+25)=3^1300 

không biết đúng không đấy

a. \(\left(-8\right).\left(-3\right)^3.125=\left(-2\right)^3.\left(-3\right)^3.5^3=\left[\left(-2\right).\left(-3\right).5\right]^3=30^3\)

b. \(27.\left(-2\right)^3.\left(-7\right).49=3^3.\left(-2\right)^3.\left(-7\right)^3=\left[3.\left(-2\right).\left(-7\right)\right]^3=42^3\)
