Answer:
7.5×10^-3
Step-by-step explanation:
[tex] \frac{ 0.027}{64000} = \frac{2.7 \times{10}^{ - 2} }{6.4 \times {10}^{4} } [/tex]
due to the law of indices :
[tex] = 4.21875 \times 10 ^{ - 7} [/tex]
don't forget
(0.027/64000)⅓
so :
[tex] ({4.21875 \times {10}^{ - 7} })^{ \frac{1}{3} } [/tex]
i.e third root of the answer above
[tex] = 7.5 \times {10}^{ - 3} [/tex]
