Write both number with the same power of 10, factor out that power of 10 (since it's common to both terms), then simplify to standard scientific notation (that is, <em>a</em>.<em>bcd</em>... × 10⁻ⁿ):

(8.28 × 10⁻⁵) - (4.1 × 10⁻⁷) = (828 × 10⁻⁷) - (4.1 × 10⁻⁷)

… = (828 - 4.1) × 10⁻⁷

… = 823.9 × 10⁻⁷

… = 8.239 × 10⁻⁵

A situation can be represented by this inequality?<br><img src="https://tex.z-dn.net/?f=1.25x%20-%206.50%20%3E%2050" id="TexForm
DochEvi [55]

There are four different choices. Now we have to find which choice best expresses the inequality 1.25x-6.50>50

1.25x has positive sign so any statement that indicates earning like sells at the rate of 1.25 will match with expression 1.25x.

Now -6.50 has negative sign that means this quantity must be subtracted or represents loss of any kind.


Keeping above sign in mind and reading the given statementns, we see that only choice "a" first the given inequality.


Hence final answer is a).
