Example 1

Example 1

  • Write in exponential form:

    2 • 2 • 2 • 2 • 2

    2?

    there are 5 two’s

    25

    Solution

  • What does exponential form mean?

  • It means to write the problem using the base and a exponent.

  • Which number is base?

  • 2 is the factor which is also the base

  • How many 2 do we have?

  • We have 5 two’s.

  • So what do you think the exponent will be?

  • The exponent will be 5

  • What do we do last?

  • Re- write the problem in exponential form.

Example 2

Example 2

  • Simplify:

    (-4)³

    (-4) • (-4) • (-4)

    12 3

    (-4) • (-4) • (-4) = -64

    Solution

  • Which number is the base?

  • The factor (-4) is the base

  • Which number is the exponent?

  • 3 is the exponent

  • What do we do first?

  • We write out the factor (-4) three times

  • How many neg. signs do we have?

  • We have 3 neg. signs.

  • Odd # of neg. signs the answer is Negative.

  • What do we do next?

  • Multiply the factor (-4) three times

-64


Example 3

Example 3

  • Simplify:

    34

    3 • 3 • 3 •3

    1 2 3 4

    3 • 3 • 3 •3 = 81

    Solution

  • Which number is the base?

  • 3 is the base

  • Which number is the exponent?

  • 4 is the exponent

  • What do we do first?

  • Write out the factor (3) four times.

  • What do we do next?

  • Multiply all the factor’s (3) together

Example 4

Example 4

  • Simplify the expression for the given values of the variable:

  • p³ - 6 for p = -3

    (-3)3+-6

    (-3) • (-3) • (-3)

    1 2 3

    (-3)• (-3) • (-3) = -27

    -27 + -6 = -33

    Solution

  • What is the first step in simplifying this expression?

  • Change the sub. Sign. Add the opp.

  • Re-write problem substituting the value of the variable (-3)

  • What do we do next?

  • Write out the factor (-3) three times

  • How many neg. signs do we have?

  • We have 3 neg. signs.

  • Odd # of neg. signs then the multiplication part of problem is neg.

  • What do we do next?

  • Follow GEMA

  • Multiply the factor (-3) three times and re-write the problem.

  • What integer rule do we use last?

  • Same signs add the #’s and keep the sign they both have.

-33


Example 5

Example 5

  • Simplify the expression for the given values of the variable:

    xp + f2forx = -4, p = 2, f = 5

    (-4)2+ (5)2

    (-4) • (-4) + (5)• (5)

    1 2

    (-4) • (-4) = 16 (5) • (5) = 25

    16 + 25 = 41

    Solution

  • What is the first step in simplifying this expression?

  • Re-write problem substituting the values for all the variables.

  • What do we do next?

  • Write out all the factors (bases) twice.

  • How many neg. signs do we have with (-4) base?

  • We have 2 neg. signs

  • Even number of neg. signs means multiplication problem is positive.

  • What do we do next?

  • Multiply each factor (base) twice

  • What integer rule do we use when adding 2 #’s?

  • Same signs you add the #’s and keep the sign they both have.
