Question

express the following numbers in usual form :

i) 3.02 x 10⁻⁶

ii) 4.5 x 10⁴

iii) 3 x 10⁸

iv) 1.0001 x 10⁹

v) 5.8 x 10¹²

Answer 1

$\mathfrak{The\:Answer\:is}$

$i)3.02 \times 10 {}^{ - 6}$

$= 302 \div 100000000$

$= 0.00000302$

$ii)4.5 \times 10 {}^{4}$

$= 45 \times 100$

$= 45000$

$iii)3 \times 10 {}^{8}$

$= 300000000$

$iv)1.0001 \times 10 {}^{9}$

$= 1000100000$

$v)5.8 \times 10 {}^{12}$

$58 \times 100000000000$

$= 5800000000000$

$\boxed{Hope\:This\:Helps}$
