Answer:

Three to the fourth means multiply 3 together 4 times, so expanded form is 3 x 3 x 3 x 3. To evaluate the power, find the product of the factors in expanded form. 3 times 3 is 9, 9 times 3 is 27, and 27 times 3 is 81.

Answer:

${3}^{4} = 81$

Step-by-step explanation:

We want to evaluate

${3}^{4}$

We have a power to evaluate.

The base is 3

The exponent is 4.

What this means it's to multiply the base by itself four times

${3}^{4} = 3 \times 3 \times 3 \times 3$

${3}^{4} = 9 \times 9 = 81$

In general, if you have aⁿ , you multiply 'a' by itself n-times.

Answer:

8 $\sqrt{13}$

Step-by-step explanation:

Using the pythagorean theorem (Assuming the house's walls are perpindicular to the ground):

a^2+b^2=c^2

we can find that 3=a and 29=c

3^2+b^2=29^2

9+b^2=841

b^2=832

b= $\sqrt{832}$

b= $\sqrt{64*13}$

b=8 $\sqrt{13}$

That is the height that the ladder will reach

plz help whats the answer to this question !!! calculate the mass of a gold bar that is 18.00cm long, 9.21cm wide, and 4.45cm hi

erik [133]

We have to find the mass of the gold bar.

We have gold bar in the shape of a rectangular prism.

The length, width, and the height of the gold bar is 18.00 centimeters, 9.21 centimeters, and 4.45 centimeters respectively.

First of all we will find the volume of the gold bar which is given by the volume of rectangular prism:

Volume of the gold bar $= length \times width\times height$

Plugging the values in the equation we get,

Volume of the gold bar $=18.00 \times 9.21 \times 4.45= 737.721cm^3$

Now that we have the volume we can find the mass by using the formula,

$Mass= density \times volume$

The density of the gold is 19.32 grams per cubic centimeter. Plugging in the values of density and volume we get:

$Mass = 19.32\times 737.721=14252.769$ grams

So, the mass of the gold bar is 14252.769 grams
