5.) (1/4)^2 x 1/4
(1/4)^2 is just equal to (1/4)x(1/4)
so this is actually: (1/4) x (1/4) x (1/4)
which is equal to: (1/12)
6.) m^50 x m^2
in this case, when the same variables with exponents are multiplied to each other, you just add the exponents
which is equal to m^52
7.) 7b3 x 4b4
This time, you multiply the number and add the exponents.
which is equal to: 28b^7
Hope I helped. :)
