Answer 1

\(c,\left(-5x^2yz^3\right)^2.4x^3y^2\)

\(=\left(25.x^4.y^2.z^6\right).4x^3y^2\)

\(=\left(25.4\right).\left(x^4.x^3\right).\left(y^2.y^2\right).z^6\)

\(=100x^7y^4z^6\)

Answer 2

c) \(\left(-5x^2yz^3\right)^2\cdot\left(4x^3y^2\right)\)

\(=25x^4y^2z^6\cdot4x^3y^2\)

\(=\left(4\cdot25\right).\left(x^4\cdot x^3\right).\left(y^2.y^2\right).z^6\)

\(=100x^7y^4z^6\)
