Simplify $0.5p\times10^{7} + 3\times10^{6}$ , where $0 < p < 1$ , leaving your answer in terms of $p$ and in standard form.

It won't just hand you the answer — it asks where you're stuck.How the checker works

Worked solution

1. Rewrite both terms with the same power of 10 and combine the coefficients.

$0.5p\times10^7=5p\times10^6$

So,

$0.5p\times10^7+3\times10^6=5p\times10^6+3\times10^6=(5p+3)\times10^6$

Answer

$(5p+3)\times10^6$
