Example Question #11 : Simple Exponents

Expand:

3^4

Possible Answers:

3*4

3*4*3*4

4*4*4

3^4*3^4*3^4*3^4

3*3*3*3

Correct answer:

3*3*3*3

Explanation:

When we expand exponents, we simply repeat the base by the exponential value.

Therefore:

3^4=3*3*3*3

Example Question #12 : Simple Exponents

Expand:

2^8

Possible Answers:

8*8

2^8*2^8*2^8*2^8*2^8*2^8*2^8*2^8*

2*2*2*2*2*2*2*2

2*2*2*2*2*2*2

2*8

Correct answer:

2*2*2*2*2*2*2*2

Explanation:

When we expand exponents, we simply repeat the base by the exponential value.

Therefore:

2^8=2*2*2*2*2*2*2*2

Example Question #14 : Simple Exponents

Expand:

$5^{-4}$

Possible Answers:

-5*4

5*4*-5*-4

$\frac{1}{5}*\frac{1}{5}*\frac{1}{5}*\frac{1}{5}$

-5*-5*-5*-5

4*4*4*4*4

Correct answer:

$\frac{1}{5}*\frac{1}{5}*\frac{1}{5}*\frac{1}{5}$

Explanation:

When exponents are negative, we can express them usinf the following format: $x^{-a}=\frac{1}{x^a}$

in this formula, is a positive exponent and is the base.

We can express $5^{-4}$ as $(5^{-1})^4$ , which is also the same as:

$\frac{1}{5}*\frac{1}{5}*\frac{1}{5}*\frac{1}{5}$

Example Question #15 : Simple Exponents

Evaluate:

$8^{-3}$

Possible Answers:

$\frac{1}{512}$

$-\frac{1}{512}$

512

Correct answer:

$\frac{1}{512}$

Explanation:

When exponents are negative, we can express them usinf the following format: $x^{-a}=\frac{1}{x^a}$

in this formula, is a positive exponent and is the base.

Therefore:

$8^{-3}=\frac{1}{8}*\frac{1}{8}*\frac{1}{8}=\frac{1}{512}$

Example Question #1 : Write And Evaluate Numerical Expressions With Exponents: Ccss.Math.Content.6.Ee.A.1

Simplify:

5^5+5^5+5^5+5^5+5^5

Possible Answers:

25^5

5^6

5^7

$5^{20}$

$5^{25}$

Correct answer:

5^6

Explanation:

When adding exponents, we first need to factor common terms.

Let's start by factoring out the following:

5^5

Factor.

5^5+5^5+5^5+5^5+5^5=5^5(1+1+1+1+1)=5^5(5)=5^6

Possible Answers:

4*7*4*7

4*4*4*4*4*4*4

7*4

7*7*7*7

7*7*7*7*7*7*7

Correct answer:

7*7*7*7
