We we multiply we add exponents of like bases. Of course we multiply constants.
7z²5z⁴d³d⁸ =(7)(5)z²z⁴d³d⁸ = 35z²⁺⁴d³⁺⁸ = 35z⁶d¹¹
Answer: 35z⁶d¹¹
Make up a problem?
(-2x²yz)(3xy²z)(4xyz²) = (-2)(3)(4) x²⁺¹⁺¹y¹⁺²⁺¹z¹⁺¹⁺² = -24x⁴y⁴z⁴
How do I know it's right? I guess from doing a lot of them; these aren'tthat hard.
