Explanation:
We need to solve [tex](5.87\times 10^7)(4.2\times 10^{11})[/tex]
Firstly, multiplying 5.87 and 4.2 = 24.654
Now taking exponent of 10.
We know that : [tex]x^a{\cdot} x^b=x^{a+b}[/tex]
It means, [tex]10^7{\cdot} 10^{11}=10^{11+7}=10^{18}[/tex]
So,
[tex](5.87\times 10^7)(4.2\times 10^{11})=24.654\times 10^{18}[/tex]
In scientific notation,
[tex](5.87\times 10^7)(4.2\times 10^{11})=2.4654\times 10^{19}[/tex]
Hence, the value of [tex](5.87\times 10^7)(4.2\times 10^{11})[/tex] is [tex]2.4654\times 10^{19}[/tex]
