Question

solve 1: (-mn8)2
2: (3x3y)2(-4x2y4)3
3: 10 times x to the 4th power times y squared all divided by -5 x to the 3rd times y squared. The entire quantity is raised to the 3rd power.

Answer 1

help

Answer 2

11. is that squared?

Answer 3

yes

Answer 4

ok square everything in the ( )

Answer 5

-m^2n^264 -64m^2n^2

Answer 6

2. (3x3y)^2 will give (9xy)^2=9^2x^2y^2==81x^2y^2
(-4x^2y^4)^3 gives (-4^3)(x^2*3)(y^4*3)= -64x^6y^12

Now multiply (81*-64)(x^2+x^6)(y^2+y^12)= -5184x^8y^14

Answer 7

3. 10x^4(y^2)/(-5x)^3y^2
the y^2 cancel because theres one in both the numerator and the denominator
this leaves:

10x^4/-125x^3
reduce and you get-2x/25
10x^4/(-5^3)x^3=10x^4/-125x^4
simplified leaves -2x/25
