Answer:

a) 2^{3}

b) 2^{5}

c) 2^{8}

d) \frac{5}{2^{3} }

e) 2^{4} + 2^{3}

Step-by-step explanation:

a) 8 = 2 x 2 x 2

b) 32 = 2 x 2 x 2 x 2 x 2

c) 256 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

d) 5 x 2^3 / 64 = 5 x 8 / 64

                        = 40/64

                        = 5/8

                        = \frac{5}{2^{3} }

e) 16 - (-2)^3 = 16 - (-8)

                    = 16 + 8

Someone help me with this show work
kakasveta [241]
The equation has three factors and equals zero
One of the factors must be zero.
Either 3x = 0 which means x = 0
or x - 4 = 0 which means x = 4
or 3x + 5 = 0 which means 3x = -5 so x = -5/3

The answer is C

E cannot be correct in this question as you are asked to “solve” and not just pick a correct option

PLS Help me Error Analysis
Maksim231197 [3]

we have

<u>Pieces of mail delivered in December by the US postal service</u>

7.14*10^{10}

<u>Pieces of mail delivered in January by the US postal service</u>

3.21*10^{10}

To find the total mail delivered for these two months, sum the two quantities

so

7.14*10^{10}+3.21*10^{10}=(7.14+3.21)*10^{10}\\=10.35*10^{10} \\=(1.035*10)*10^{10} \\=1.035*(10* 10^{10})\\=1.035*10^{(10+1)} \\= 1.035*10^{11}

therefore

the correct solution is 1.035*10^{11}

the error is in this part

10.35*10^{10}

To move decimal over one place 10 to the power of 10 should be 10 to the power of 11

1.035*10^{10}
