The little three above the 2 represents how many times you should multiply 2 to itself.

2³ = 8, because it's the same as 2 × 2 × 2 (notice how 2 has been multiplied by 2, 3 times).

So now that you know 2³ = 8, you just need to add 4, which is just 8 + 4 = 12.

Simplify without parentheses (4v-3w)^2 Explain.

Lilit [14]

(4v-3w)∧2, Its to the second power so take the exponent 2 and put it on the variables and coefficients so you would have (4∧2)(v∧2)-(3∧2)(w∧2). Then you would do the math and get 16v∧2-9w∧2 than you would add the like terms so you have 25v∧2w∧2.

Problem page the length of a rectangle is four times its width. if the perimeter of the rectangle is 70 cm , find its area.

agasfer [191]

So we can call the width of the rectangle x.
So then the length would be 4x.
The perimeter would then be 10x.
Since the perimeter is 70, we can say 70 = 10x.
And then simplify that to 7 = x.
So the length of a rectangle would be 28 cm, and the width would be 7.
So to find the area, just multiply length by width.
28*7 = 196 square cm
So the rectangle's area is 196 square cm.

I hope I helped!
