Question

Express the following numbers in scientific nations.
a. $56700000000$

b. $98400000\times {10}^4$

c. $0.00000278$
d. $14crores$

e. $37Lakhs$

f. $585$ thousands

Answer 1

$(a.)$

$=>56700000000=5.67\times {10}^{10}$

$(b.)$

$=>98400000=9.84\times {10}^7$

$(c.)$

$=>0.00000278==\frac{278}{{10}^8}$

$=>\frac{2.78\times {10}^2}{{10}^8}$

$2.78\times {10}^{-}6$

$(d.)$

$=>140000000=1.4\times {10}^8$

$=>3700000=3.7\times {10}^6$

$(f.)$

$=>585000=5.85\times {10}^5$
