Question 8(i)
Compare the following numbers:
(i) $2.7\times {10}^{12};1.5\times {10}^8$

Answer 1

(i) $2.7\times {10}^{12}and1.5\times {10}^8$

In case of ${10}^{12}$ the exponent is 12 and in case of ${10}^8$, the exponent is 8.
On comparing the exponents of base 10,
$2.7\times {10}^{12}>1.5\times {10}^8$
