evaluate. express your answer in scientific notation. $3.5 \\times 10^{-2} + 0.29$

Explanation:

Step1: Convert scientific notation to decimal

$3.5\times10^{-2} = 3.5\div100 = 0.035$

Step2: Add the two decimal numbers

$0.035 + 0.29 = 0.325$

Step3: Convert the result to scientific notation

To write $0.325$ in scientific notation, we move the decimal point one place to the right to get $3.25$, and since we moved it one place, the exponent of 10 is $-1$. So $0.325 = 3.25\times10^{-1}$

Answer:

$3.25\times10^{-1}$
