What is the laws of exponents?

Sagot :

Answer:

LAWS OF EXPONENTS

I. Product Of Powers

If the expressions multiplied have the same base, add the exponents.

x^{a} \: • \: x ^{b} = x^{a+b}x

a

•x

b

=x

a+b

II. Power Of A Power

If the expression raised to a number is raised by another number, multiply the exponents.

(x^{a})^{b} = x^{ab}(x

a

)

b

=x

ab

III. Power Of A Product

If the multiplied expressions is raised by a number, multiply exponents then multiply the expressions.

\begin{gathered}(x^{a}x^{b})^{c} = x^{ac} \: x^{bc} \\ (xy)^{a} = x^{a} y^{a}\end{gathered}

(x

a

x

b

)

c

=x

ac

x

bc

(xy)

a

=x

a

y

a

IV. Quotient Of Power

If the ratio of two expressions is raised to a number, then

Case 1. \displaystyle \frac{x^{a}}{x^{b}} = \displaystyle x^{a+b}

x

b

x

a

=x

a+b

, where a > b.

Case 2. \displaystyle \frac{x^{a}}{x^{b}} = \displaystyle \frac{1}{x^{b-a}}

x

b

x

a

=

x

b−a

1

, where a < b

Answer:

Definition of law of exponents;

one of a set of rules in algebra: exponents of numbers are added when the numbers are multiplied, subtracted when the numbers are divided, and multiplied when raised by still another exponent:

Step-by-step explanation:

am×aⁿ=am+n; am÷aⁿ=am−n; (am)ⁿ=amn.
