5 answers

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

= d^19

Thanks. Another one:

(z^8)^0 z^5

ANYTHING AT ALL^0 = ONE
so
z^5
