Exponentiation is the requirement for the number to be multiplied by itself several times.

Exponentiation is the requirement for the number to be multiplied by itself several times.

A root is the inverse operation of exponentiation, which helps us discover which number multiplied by itself gives this result.

The square root is equal to the power of 0.5.

Question 1

What is the answer to the following?

\( 3^2-3^3 \)

Question 2

Sovle:

\( 3^2+3^3 \)

Question 3

\( \sqrt{441}= \)

Question 4

Find the value of n:

\( 6^n=6\cdot6\cdot6 \)?

Question 5

In the figure in front of you there are 3 squares

Write down the area of the shape in potential notation

What is the answer to the following?

$3^2-3^3$

Remember that according to the order of operations, exponents come before multiplication and division, which come before addition and subtraction (and parentheses always before everything),

So **first** **calculate** the values of the terms in the power **and then** subtract between the results:

$3^2-3^3 =9-27=-18$__Therefore, the correct answer is option A.__

$-18$

Sovle:

$3^2+3^3$

Remember that according to the order of operations, exponents precede multiplication and division, which precede addition and subtraction (and parentheses always precede everything).

So **first** **calculate** the values of the terms in the power **and then** subtract between the results:

$3^2+3^3 =9+27=36$__Therefore, the correct answer is option B.__

$\sqrt{441}=$

The root of 441 is 21.

$21\times21=$

$21\times20+21=$

$420+21=441$

$21$

Find the value of n:

$6^n=6\cdot6\cdot6$?

We use the formula: $a\times a=a^2$

In the formula, we see that the power shows the number of terms that are multiplied, that is, two times

Since in the exercise we multiply 6 three times, it means that we have 3 terms.

Therefore, the power, which is n in this case, will be 3.

$n=3$

In the figure in front of you there are 3 squares

Write down the area of the shape in potential notation

Using the formula for the area of a square whose side is b:

$S=b^2$In the problem of the drawing, three squares whose sides have a length: 6, 3, and 4, units of length from left to right in the drawing respectively,

Therefore the areas are:

$S_1=3^2,\hspace{4pt}S_2=6^2,\hspace{4pt}S_3=4^2$square units respectively,

Therefore, the total area of the shape, composed of the three squares, is as follows:

$S_{\text{total}}=S_1+S_2+S_3=3^2+6^2+4^2$square units

__Therefore, we recognize through the substitution property in addition that the correct answer is answer C.__

$6^2+4^2+3^2$
