Math Problem Statement

Evaluate each of the following expressions: (-2)^6, (-3)^3, (-10)^5, (-4)^2, (-1)^44

Solution

Let's evaluate each of the expressions given:

  1. (2)6(-2)^6:

(2)6=(2)×(2)×(2)×(2)×(2)×(2)(-2)^6 = (-2) \times (-2) \times (-2) \times (-2) \times (-2) \times (-2)

Calculating step-by-step:

(2)×(2)=4(-2) \times (-2) = 4

4×(2)=84 \times (-2) = -8

8×(2)=16-8 \times (-2) = 16

16×(2)=3216 \times (-2) = -32

32×(2)=64-32 \times (-2) = 64

So, (2)6=64(-2)^6 = 64.

  1. (3)3(-3)^3:

(3)3=(3)×(3)×(3)(-3)^3 = (-3) \times (-3) \times (-3)

Calculating step-by-step:

(3)×(3)=9(-3) \times (-3) = 9

9×(3)=279 \times (-3) = -27

So, (3)3=27(-3)^3 = -27.

  1. (10)5(-10)^5:

(10)5=(10)×(10)×(10)×(10)×(10)(-10)^5 = (-10) \times (-10) \times (-10) \times (-10) \times (-10)

Calculating step-by-step:

(10)×(10)=100(-10) \times (-10) = 100

100×(10)=1000100 \times (-10) = -1000

1000×(10)=10000-1000 \times (-10) = 10000

10000×(10)=10000010000 \times (-10) = -100000

So, (10)5=100000(-10)^5 = -100000.

  1. (4)2(-4)^2:

(4)2=(4)×(4)(-4)^2 = (-4) \times (-4)

(4)×(4)=16(-4) \times (-4) = 16

So, (4)2=16(-4)^2 = 16.

  1. (1)44(-1)^{44}:

Since the exponent is even, (1)(-1) raised to any even power is 11.

(1)44=1(-1)^{44} = 1

So, (1)44=1(-1)^{44} = 1.

In summary, the evaluated expressions are:

  1. (2)6=64(-2)^6 = 64
  2. (3)3=27(-3)^3 = -27
  3. (10)5=100000(-10)^5 = -100000
  4. (4)2=16(-4)^2 = 16
  5. (1)44=1(-1)^{44} = 1

Would you like further details or have any questions?

Here are some related questions:

  1. What happens when you raise a negative number to an odd power?
  2. How does raising a number to an even power affect its sign?
  3. What is the value of (5)4(-5)^4?
  4. Calculate (7)3(-7)^3.
  5. What is the result of (1)99(-1)^{99}?

Tip: The sign of a negative number raised to a power depends on whether the exponent is odd or even. If the exponent is odd, the result will be negative; if it's even, the result will be positive.
