Question

What is the largest number?

a) -7% 104
b) – 7x10⁻4
c) 7 x 10⁻4
d) 7 * 10⁻30

Answer 1

The largest number among the options provided, ignoring the apparent typo in option a, is option c) 7 x 10⁻⁴, which is the only positive number and equivalent to 0.0007 in standard notation.

Step-by-step explanation:

To determine the largest number, we must understand each expression correctly:

1. -7% 104 is somewhat unclear but seems to be a mistake and not relevant to the comparison.
2. -​7 x 10⁻⁴ is – 0.0007.
3. 7 x 10⁻⁴ is 0.0007.
4. 7 * 10⁻³⁰ is an extremely small positive number.

Option c) 7 x 10⁻⁴ is the largest number because it is the only positive number among those listed (ignoring option a, which appears to be a typo).
