XLiV represents 64 true ya false​
V125BC [204]

Answer:

False

Step-by-step explanation:

Given

XLIV = 64

Required

True or False

The above numeral can be split as follows:

XLIV = XL + IV

X means 10 and L means 50.

But because X (10) which is smaller comes before L (50), XL is executed as:

XL = -10 + 50

XL = 40

In Roman numerals;

IV = 4

Substitute 40 for XL and 4 for IV.

XLIV = 40 + 4

XLIV = 44

Hence;

<em />XLIV = 64<em> is false</em>
