Question

express the 1.25× 10^7÷5×10^3 in the form k×10^n.​

Answer 1

Step-by-step explanation:

$given \: that \\ 1.25 \times {10}^{7 } \div 5 \times {10}^{3} \\ = > \frac{1.25}{5} \times \frac{ {10}^{7} }{{10}^{3} } \\ = > 0.25 \times \frac{ {10}^{7} }{ {10}^{3} } \\ </em></strong><strong><em> \\ = > 0.25 \times {10}^{7 - 3 } \\ = > 0.25 \times {10}^{4} \\ = > \frac{25}{100} \times {10}^{4} \\ = > \frac{25}{ {10}^{2} } \times {10}^{4} \\ = > 25 \times \frac{ {10}^{4} }{ {10}^{2} } \\ = > 25 \times {10}^{4 - 2 } \\ = > 25 \times {10 }^{2}$

The value is 25×10²=k×10^n

k=25 and n=2
