Write as a monomial in standard form (−4x^2ya^3)^2

svetoff [14.1K]

The given monomial in standard form is $16a^6x^4y^2$

Solution:

A Monomial in standard form is the product of one or more factors: a constant coefficient and one factor for each variable in the expression.

Given monomial is:

$(-4x^2ya^3)^2$

We use the following law of exponents to solve the above monomial:

$(ab)^n = a^nb^n\\\\(a^n)^m = a^{mn}$

Using these in given monomial, we get

$(-4x^2ya^3)^2 = (-4)^2(x^2)^2(y)^2(a^3)^2$

Now applying the law of exponent $(a^n)^m = a^{mn}$ we get,

$(-4)^2(x^2)^2(y)^2(a^3)^2 = 16x^{2 \times 2}y^2a^{3 \times 2} = 16x^4y^2a^6$

A monomial is in standard form when its term of highest degree is first, its term of 2nd highest is 2nd etc

Writing in standard form we get,

$\rightarrow 16a^6x^4y^2$

Thus the given monomial is written in standard form

Y=-3x + 6 What is the slope? And what would the points be on a graph

katen-ka-za [31]

The slope is -3 and the points would start at 6 which is the y intercept. you would plot a point at (0,6) then from there you would go up 3 and left one and continue this pattern. the line goes left because the slope is negative
