Question

$0.0024+2400+12.3$ can be written as

• A. $2.4\times {10}^{-3}+2.4\times {10}^{-3}+1.23\times {10}^{-1}$
• B. $2.4\times {10}^{-3}+2.4\times {10}^3+1.23\times {10}^{-1}$
• C. $2.4\times {10}^3+2.4\times {10}^3+1.23\times {10}^1$
• D. $2.4\times {10}^{-3}+2.4\times {10}^{-3}+1.23$

Answer 1

The correct option is B $2.4\times {10}^{-3}+2.4\times {10}^3+1.23\times {10}^{-1}$

Standard Form of
0.0024 = $2.4\times {10}^{-3}$
2400 = $2.4\times {10}^3$
12.3 = $1.23\times {10}^{-1}$
So, we can write: $0.0024+2400+12.3$ as $2.4\times {10}^{-3}+2.4\times {10}^3+1.23\times {10}^{-1}$
