Question

Simplify the expression using positive exponents.
[b^4]3
[c^9]
(thats is a fraction.)

so like, b to the fourth divided by c to the ninth and it's all to the third.

I hope this makes sence.
Please help,

Answer 1

The rule of exponents you need is ( a^x )^y = a^(xy)

[ ( b^4 ) / ( c ^ 9 ) ]^3

( b^4 )^3 / ( c^9 )^3

b^12 / c^18
