How do you simplify #(5^-1)(3^3)#?

Answer 1

Eva Abramson

#(5^-1)(3^3)=color(green)(27/5)=color(green)(5.4)#

#(5^-1)=(1/5^1)=(1/5)#

#(3^3)=(3xx3xx3)=(27)#

Therefore #color(white)("XXX")(5^-1)(3^3)=(1/5)xx(27)=27/5#

...or if you want this as a decimal fraction: #color(white)("XXX")27/5=54/10=5.4#
