Final answer:
7.1x10⁻² in ordinary decimal format is 0.071. It is done by multiplying the decimal number 7.1 with the power of ten, which is 0.01 in this case.
Step-by-step explanation:
The question asks to convert the scientific notation 7.1x10⁻² into an ordinary decimal number. Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. It is commonly used in mathematics and science. In scientific notation, numbers are written as a product of two factors: a decimal number (between 1 and 10) and a power of ten. Here, 7.1 is the decimal number and 10⁻² represents the power of ten, which is 1/100 or 0.01. Multiplying these, we get:
7.1 x 10⁻² = 7.1 x 0.01 = 0.071
Therefore, 7.1x10⁻² as an ordinary number is 0.071.
