Answer:
[tex]x = 4 \times {10}^{2} [/tex]
Step-by-step explanation:
Let the number be 'x'.
According to the question ,
[tex](4 \times {10}^{3} ) \times x = 16 \times {10}^{5} [/tex]
Dividing both the sides by 4 × 10³ :-
[tex] = > \frac{4 \times {10}^{3} \times x}{4 \times {10}^{3} } = \frac{16 \times {10}^{5} }{4 \times {10}^{3} } [/tex]
[tex]=> x = \frac{16}{4} \times (10^{5-3})[/tex]
[tex] = > x = 4 \times {10}^{2} [/tex]
