Question

Can someone please help me in this question.

Write each of these numbers as powers of 2.
a) 8
b) 32
c) 256
d)
$\frac{(5x2^{3})}{64}$
e)
$16 - ( - 2)^{3}$

​

Answer 1

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

                    = $2^{4} + 2^{3}$
