Question

3.28×10 = 3.28×10² = 3.28×10³ = 3.28×10⁴ = solve.

Explanation:

Step1: Recall scientific - notation multiplication rule

For a number in scientific - notation \(a\times10^{n}\), when multiplying, we multiply the coefficients and add the exponents of 10.

Step2: Calculate \(3.28\times10\)

\(3.28\times10 = 32.8\)

Step3: Calculate \(3.28\times10^{2}\)

\(3.28\times10^{2}=3.28\times100 = 328\)

Step4: Calculate \(3.28\times10^{3}\)

\(3.28\times10^{3}=3.28\times1000 = 3280\)

Step5: Calculate \(3.28\times10^{4}\)

\(3.28\times10^{4}=3.28\times10000 = 32800\)

Answer:

\(3.28\times10 = 32.8\), \(3.28\times10^{2}=328\), \(3.28\times10^{3}=3280\), \(3.28\times10^{4}=32800\)
