Question

Help, please simplify.. thank you

Answer 1

`\bf \cfrac{3.7* 10^(-12)(42)}{(.000000025)(4.0* 10^(-15))}\implies \cfrac{37* 10^(-13)(42)}{(25* 10^9)(4* 10^(-15))}`


`\bf \cfrac{37(42)* 10^(-13)}{25(4)* 10^910^(-15)}\implies \cfrac{1554* 10^(-13)}{100* 10^(9-15)}\implies \cfrac{1554* 10^(-13)}{1* 10^2* 10^(9-15)} \\\\\\ \cfrac{1554* 10^(-13)}{10^(2+9-15)}\implies \cfrac{1554* 10^(-13)}{10^(-4)}\implies 1554* 10^(-13)* 10^4 \\\\\\ 1554* 10^(-13+4)\implies 1554* 10^(-9)\implies \cfrac{1554}{10^9}\implies 0.000001554`
