Question

Write the following numbers in the usual form:

(i) $4.83\times {10}^7$ (ii) $3.02\times {10}^{-6}$

(iii) $4.5\times {10}^4$ (iv) $3\times {10}^{-8}$

(v) $1.0001\times {10}^9$ (vi) $5.8\times {10}^2$

(vii) $3.61492\times {10}^6$ (viii) $3.25\times {10}^{-7}$

Answer 1

$\left(i\right)4.83\times {10}^7=4.83\times 10000000=48300000\left(ii\right)3.02\times {10}^{-6}=\frac{3.02}{{10}^6}=\frac{3.02}{1000000}=0.00000302\left(iii\right)4.5\times {10}^4=4.5\times 10000=45000\left(iv\right)3\times {10}^{-8}=\frac{3}{{10}^8}=\frac{3}{100000000}=0.00000003\left(v\right)1.0001\times {10}^9=1.0001\times 1000000000=1000100000\left(vi\right)5.8\times {10}^2=5.8\times 100=580\left(vii\right)3.61492\times {10}^6=3.61492\times 1000000=3614920\left(viii\right)3.25\times {10}^{-7}=\frac{3.25}{{10}^7}=\frac{3.25}{10000000}=0.000000325$
