Find (2.2 x 107)(5 x 108) (2.5 x 103)(8.8 x 105) expressed in scientific notation.
Answer:
Scientific notation of the multiplication is \(2.42\times 10^{25}\)
Step-by-step explanation:
\((2.2\times 10^{7})(5\times 10^{8})(2.5\times 10^{3})(8.8\times 10^{5} )\)
= \((2.2\times 5\times 2.5\times 8.8)10^{(7+8+3+5)}\)
[Since \(10^{a}\times 10^{b}=10^{(a+b)}\)]
= \(242\times 10^{23}\)
= \(2.42\times 10^{25}\)
Therefore, the scientific notation of the multiplication is \(2.42\times 10^{25}\)
