Question

Simplify 5x(3e" class="latex-formula">y)³ . Give a written explanation of how you simplified

Answer 1

Exlanation
remember

$(ab)^c=(a^c)(b^c)$
and
$(x^m)^n=x^{mn}$
and
$(x^m)(x^n)=x^{m+n}$


so

$5x(3x^4y)^3=5x(3^3)((x^4)^3)(y^3)=5x(27)(x^{12})(y^3)=135x^{13}y^3$

Answer 2

$5x(3 x^{4} y)^3=5x\cdot 27x^{12}y^3=135x^{13}y^3$
