Question

make it soundl like a 7 year old made this To simplify \((2a^{5}a^{4})^{3}\), we first look inside the parentheses and combine the \(a\) terms by adding their exponents, \(5\) plus \(4\), which gives us \(2a^{9}\) inside the brackets. Then we take that whole thing to the power of \(3\), which means we multiply the number \(2\) by itself three times to get \(8\) and multiply the exponent \(9\) by \(3\) to get \(27\). When we put it all together, the final answer is \(8a^{27}\).

Answer 1

First I look inside the ( ) and see 2 a^5 a^4. I add 5 and 4 and get 9, so it’s 2a^9. Then I do the power 3, which is like doing it three times: 2×2×2 = 8 and 9×3 = 27. So the answer is 8a^27. Ta‑da!
