a) \(\left(-5\right)^5\)
b) \(\left(-2\right)^3.\left(-3\right)^3\)
a,(-5).(-5).(-5).(-5).(-5)=(-5)5
b,(-2).(-2).(-2).(-3).(-3).(-3)=(-2)3.(-3)3
Tk mk nhé!Thank you!
A\(\left(-5\right)^5\)
B\(\left(-2\right)^3\cdot\left(-3\right)^2\)
A ) \(\left(-5\right)^5\)
B ) \(\left(-2\right)^3.\left(-3\right)^3\)
\(a.\left(-5\right).\left(-5\right).\left(-5\right).\left(-5\right).\left(-5\right)\)
\(=\left(-5\right)^2\times\left(-5\right)^2\times\left(-5\right)\)
\(=\left(-5\right)^4\times\left(-5\right)\)
\(=\left(-5\right)^5\)
\(b.\left(-2\right).\left(-2\right).\left(-2\right).\left(-3\right).\left(-3\right).\left(-3\right)\)
\(=\left[\left(-2\right).\left(-3\right)\right].\left[\left(-2\right).\left(-3\right)\right].\left[\left(-2\right).\left(-3\right)\right]\)
\(=6.6.6=6^3\)
Viết các tích sau dưới dạng 1 lũy thừa :
a. ( -5 ) .( -5 ) . ( -5 ) . ( -5 ) . ( -5 ) = ( -55 )
b, ( -2 ) . ( -2 ) . ( -2 ) . ( -3 ) . ( -3 ) . ( -3 ) = ( -23 ) . ( -33 )
Chúc bạn học tốt!!! ^_^
