(Problem Number Five Answer: Simplify exponent so you get -3)
(Problem Number Seven Answer:
Step 1: Simplify brackets
\(4 x^{2} y^{3} *7xy\)
Step 2: Gather like terms
\(4 * 7 x^{2} x y^{3} y\)
Step 3: Use Product Rule \(x^{a} x^{b= x^{a+b} }\)
\(4* 7 x^{2+1} y^{3+1}\)
Step 4: Simplify 2+1 to 3
\(4*7 x^{3} y^{3+1}\)
Step 5: Simplify 3 + 1 to 4
\(4*7 x^{3} y^{4}\)
Step 6: Simplify
\(28 x^{3} y^{4}\)
Done! :)
