Pre-Algebra
It seems like you're multiplying these together and if that is the case you will be adding the exponents. So, -10 + 5 will equal -5. Since it's asking for the answer to have positive exponents you will just have to show that b^-5 = (1/b^5) and there is your answer.

recall that a-b = 1/ab so 10-2 = 1/102 = 1/100 not sure what you mean by 'standard form' as it relates to powers, only positive exponents? if so, then my second last line of the above answer should do it.

subtract. express your answer in simplest form (2)/(5) minus (y)/(y-2) (2/5)-(y)/(y-2) Multiply by 5(y-2) [2(y-2)] - 5y Clear the fraction and combine terms.

X^-6 times X^5= X^-1 (add exponents -6 + 5=-1 X to the negative 1 can be rewritten 1/X so you have only postitve exponents. Y^-12 divided by Y^5 = Y^-17 (subtract exponents -12-5=-17) So Y^-17=1/Y^17
