Question

Simplyfy
(i):- (64)-1/3
(ii):- (125)1/3
():- (121/256)-1/2​

Answer 1

Answer:

i) 0.25

ii) 5

iii) 0.45

Step-by-step explanation:

i) $64^{ - \frac{1}{3}}$

$= \frac{1}{64^{ \frac{1}{3} } }$

$= \frac{1}{ \sqrt[3]{64} }$

$= \frac{1}{ \sqrt[3]{2 \times 2 \times 2 \times 2 \times 2 \times 2} }$

$= \frac{1}{2 \times 2}$

$= \frac{1}{4} = 0.25$

ii) ${125}^{ \frac{1}{3} }$

$= \sqrt[3]{125}$

$= \sqrt[3]{5 \times 5 \times 5}$

$= 5$

iii) $\frac{121}{256}^{ - \frac{1}{2} }$

$= \frac{256^{ \frac{1}{2} }}{121^{ \frac{1}{2} }}$

$= \frac{ \sqrt{ 256}}{ \sqrt{121 }}$

$= \frac{ \sqrt{16 \times 16} }{ \sqrt{11 \times 11} }$

$= \frac{16}{11}$

$= 0.4545$
