Answer:

-9.5

Step-by-step explanation:

We can create an equation to represent this, where n is the missing value.

2n - 2 = -21

Now we can solve for n by isolating it on one side of the equation.

Add 2 to both sides:

2n - 2 + 2 = -21+2\\\\2n = -19

Divide both sides by 2:

2n\div2 = -19\div2\\\\n = -9.5

Hope this helped!

In Exercise, use the properties of exponents to simplify the expression.<br> (e3)4
Morgarella [4.7K]

Answer:

Answer will be e^{12}

Step-by-step explanation:

We have given the expression (e^3)^4

We have to simplify this expression with the help of property of exponent

According to property of exponent when there is exponent to exponenet then both the exponent are multiplied with each other

So (e^3)^4=e^{3\times 4}=e^{12}

Here 4 and 3 are exponent to exponent so these are multiplied with each other
