Explain in a complete sentence how to tell the difference between the power of power and the power of product rule. Please help
german

Answer:


Step-by-step explanation:

The power of a power rule is when power is raised to another power. (x^n)^m.  when you do this rule, you must multiply the exponents so, x^nm or x^n*m.

The product rule for exponents is used when there are multiple terms that are raised by an exponent that have the same base and ae being multiplied. x^3 * x^2. To solve this, you keep the base (x) and add the two exponents together (3 and 2) so, x^3+2 = x^5.

Hope this helped (:
