@phi
this is an "order of operations" problem have you learned order of operations? Here I would first do what is in the parens

yes, so you now have \[ 3 \cdot 9^3 \] what operation do you do next? remember PEDMAS (or whatever they teach you) ? Parens, Exponents, Divide/Multiply, Add/Subtract
the next step is to "do the exponent" which means figure out \[ 9^3\] which means figure out 9*9*9
