Question

Harold starts to simplify the expression below, as shown, but his work is not correct. –x(6x5)2(–2y6)(y) (–6x6)2(–2y6)(y) what should harold have done instead? combined like terms squared brainly

Answer 1

squared 6x^5
and when you simplify the expression you get
72x^11y^7

Answer 2

Answer: He should first solve the bracket by squaring $(6x^5)$ then multiply it by x.

Step-by-step explanation:

Here the given expression is, $-x(6x^5)^2(-2y^6)(y)$

And, we can write,

 $-x(6x^5)^2(-2y^6)(y)$=  $-x \times 6^2 \times x^{10}\times -2y^6\times y$ ( by solving the bracket)

⇒$-x(6x^5)^2(-2y^6)(y)$=  $-36 x^{10+1}\times -2y^{6+1}$ ( Because, $x^m.x^n=x^{m+n}$)

⇒$-x(6x^5)^2(-2y^6)(y)$=  $-36 x^{11}\times -2y^7$

⇒$-x(6x^5)^2(-2y^6)(y)$=  $72 x^{11} y^7$
