Question

Simplify the expression. (−4k4j5)3(k3j3)7

Answer 1

`\bf (-4k^4j^5)^3(k^3j^3)^7\impliedby \textit{first off, let's distribute the exponent} \\\\\\\ [(-4)^3k^(4\cdot 3)j^(5\cdot 3)]~~~(k^(3\cdot 7)j^(3\cdot 7))\implies -64k^(12)j^(15)~~~~~k^(21)j^(21) \\\\\\ -64k^(12+21)j^(15+21)\implies -64k^(33)j^(36)`
