SOMEONE PLEASE HELP ME
Ostrovityanka [42]

Answer:

28, 30, 32

Step-by-step explanation:

Three consecutive even numbers are three even numbers that are next to each other. For example, 2, 4 and 6 would be 3 consecutive even numbers.

With this sort of problem, you want to try to let each number be equal to one thing and then construct the same number of equations as you have variables:

Let's let,

Integer 1 = X

Integer 2 = Y

Integer 3 = Z

X + Y + Z = 90

We also know, that

Y = X + 2

And that

Z = X + 4

Now, we can sub these equations into the first equation. We do this so that we have everything represented as the same variable.

90 = X + (X+2) + (X+4)

90 = 3X  + 6

84 = 3X

28 = X

So, the numbers are 28, 30 and 32

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

<em><u>Solution:</u></em>

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.

<em><u>Given monomial is:</u></em>

(-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
