(-4)(-4) use an exponent to rewrite the expression

DiKsa [7]

For this case we have the following expression:
<span> $(-4)(-4) 
$
By properties of exponents we have:
Same basis, the exponents are added.
We have then:
$(-4)^{1+1}$
Then, rewriting the exponent we have:
$(-4)^{2}$
Therefore, an exponent to rewrite the expression is:
2
Answer:
$(-4)^{2}$
an exponent to rewrite the expression is 2.</span>

Let m = X^2 + 3.

Tpy6a [65]

The Equation in terms of m, m^2+7m+10=0

What is substituting in the equation ?

substituting means changing or replacing the values in the given equation.

Calculation:

Given equation is (x^2+3)^2+7x^2+21=-10

and m= X^2 + 3.

make the given equation in the form X^2 + 3,

now,

(x^2+3)^2+7x^2+21=-10

(x^2+3)^2+7(x^2+3)=-10

where,

X^2 + 3= m

after putting the value or replacing the values

we get, m^2+7m=-10

m^2+7m+10=0

the above equation is in the form of "m".

The Equation in terms of m, m^2+7m+10=0
