Example Question #4 : Expressions & Equations

Simplify:

\displaystyle 5^5+5^5+5^5+5^5+5^5

Possible Answers:

\displaystyle 25^5

\displaystyle 5^7

\displaystyle 5^{20}

\displaystyle 5^6

\displaystyle 5^{25}

Correct answer:

\displaystyle 5^6

Explanation:

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

Let's start by factoring out the following:

\displaystyle 5^5

Factor.

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

Example Question #212 : Exponents

Expand:

\displaystyle 7^4

Possible Answers:

\displaystyle 7*7*7*7

\displaystyle 7*4

\displaystyle 4*4*4*4*4*4*4

\displaystyle 4*7*4*7

\displaystyle 7*7*7*7*7*7*7

Correct answer:

\displaystyle 7*7*7*7

Explanation:

When a number is raised by an exponent, the base value is multiplied by itself the number of times that the exponential value indicates.

\displaystyle 7^4=7*7*7*7

Example Question #11 : Simple Exponents

Expand:

\displaystyle 8^5

Possible Answers:

\displaystyle 5*5*5*5*5*5*5*5

\displaystyle 5*8

\displaystyle 5*8*8*8*8*5

\displaystyle 8*5*5*8

\displaystyle 8*8*8*8*8

Correct answer:

\displaystyle 8*8*8*8*8

Explanation:

When a number is raised by an exponent, the base value is multiplied by itself the number of times that the exponential value indicates.

\displaystyle 8^5=8*8*8*8*8

Example Question #5 : Expressions & Equations

Evaluate:

\displaystyle 2^4

Possible Answers:

\displaystyle 32

\displaystyle 6

\displaystyle 12

\displaystyle 8

\displaystyle 16

Correct answer:

\displaystyle 16

Explanation:

When a number is raised by an exponent, the base value is multiplied by itself the number of times that the exponential value indicates.

\displaystyle 2^4 is expanded to \displaystyle 2*2*2*2.

The product is \displaystyle 16.

Possible Answers:

\displaystyle 16

\displaystyle 32

\displaystyle 256

\displaystyle 128

\displaystyle 64

Correct answer:

\displaystyle 256

Explanation:

When a number is raised by an exponent, the base value is multiplied by itself the number of times that the exponential value indicates.

\displaystyle 4^4 is expanded to \displaystyle 4*4*4*4.

The product is \displaystyle 256.

Example Question #1 : Expressions & Equations

Expand: \displaystyle 9^9

Possible Answers:

\displaystyle 99*99*99*99*99*99

\displaystyle 9*9*9*9*9*9*9*9

\displaystyle 9*9

\displaystyle 9*9*9*9*9*9*9*9*9

\displaystyle 9^9*9^9*9^9*9^9*9^9*9^9*9^9*9^9*9^9

Correct answer:

\displaystyle 9*9*9*9*9*9*9*9*9

Explanation:

\displaystyle 9^9 To expand the exponent, we just multiply the base out by the exponent present.

\displaystyle 9^9=9*9*9*9*9*9*9*9*9

Example Question #1 : Expressions & Equations

Expand: \displaystyle 10^7

Possible Answers:

\displaystyle 7*10*7*10

\displaystyle 10*7
