How to solve d(d^-2)^-9? Please show and explain step-by-step.
What do you have to solve exactly? Do you by chance mean simplify?
Should there be an equal sign in the expression that you typed?
Simplify, sorry. The answer says d^19, but I don't get how.
d^1 * d^(-2*-9)
= d^1 * d^+18
Thanks. Another one:
