Question

Express the following numbers in the exponential form:
(i) $1728$
(ii) $\frac{1}{512}$
(iii $0.000169$.

Answer 1

(i) $1728=12\times 12\times 12={12}^3$

(ii) $\frac{1}{512}=\frac{1}{2\times 2\times 2\times 2\times 2\times 2\times 2\times 2\times 2}=2^{-9}$

(iii) $0.000169=0.013\times 0.013=(0.013{)}^2$
