Question

How do you simplify x4·(y2)3·y−2 and (3x)2·x2 Look at picture

Answer 1

Answer:

$9x^{4}$ for $(3x)^2$· $x^{2}$ and $(x^{4})$·$(y^{4})$ for $x^4$·$(y^2)^3$·$y^{-2}$

Step-by-step explanation:

$(3x)^{2} (x^{2} )$ Multiply in

$(9x^{2})(x^{2})$ Multiply together

$9x^{4}$

$(x^{4})(y^{2})^{3} (y^{-2})$

$(x^{4})(y^{6})(\frac{1}{y^{2}})$  Multiply in

$(x^{4})(\frac{y^{6}}{y^{2}})$ Multiply together

$(x^{4})(y^{4})$
