We have the following expression given:

$(4y^3+28y^2)+(y+7)$

We can start selecting as common factor 4y^2 and we got:

$4y^2(y+7)+(y+7)$

Now we can select y+7 as common factor and we got:

$(y+7)\left\lbrack 4y^2+1\right\rbrack$

So then our final answer would be:

$(y+7)(4y^2+1)$

I dont understand how to simplify an expression with exponents

Mashutka [201]

Answer:

3^4

Simplifying an expression with expression with exponents:

If they are dividing, we keep the base and subtract the exponents. For example:

$\frac{a^x}{a^y}=a^{x-y}$

In this question:

$\frac{3^2}{3^{-2}}=3^{2-(-2)}=3^{2+2}=3^4$
