1-digit number: 5 possibilities
2-digits number: 5 x 5 = 25 possibilities
So there are 30 numbers.

How many even 3-digit positive integers can be written using the digits 1 3 4 5 and6?
If a digit can be repeated there are 5 x 5 x 5 = 125 possible numbers If a digit cannot be repeated there are 5 x 4 x 3 = 60 possible numbers.
Define what are the integers?
Positive integers are all the whole numbers greater than zero: 1, 2, 3, 4,5,... and negative integers are-1.-2,-3.-4,-5,.... The integers are the union of the positive integers, the negative integers and 0. Integers are numbers that can be written without a fractional or decimal component, and fall within the set {... −2, −1, 0, 1, 2, ...}. A third definition is the integers are the union of the natural numbers, their negatives, and 0.
Does 43 have an exponential form?

What are positive and negative integers?
An integer is a whole number. The set of integers can be expressed as {-∞, ..., -3, -2, -1, 0, 1, 2, 3, ..., ∞}. The ∞ symbol represents infinity (an integer with infinite digits). The integer zero (0) lies at the centre of the set and is neither positive nor negative. The positive integers are the counting numbers greater than zero {1, 2, 3, ..., ∞}. The negative integers are the inverses of the counting numbers, all less than zero {-∞, ..., -3, -2, -1}. Positive integers are sometimes denoted with the + symbol for clarity, such as {+1, +2, +3, ..., +∞).Positive integers are the counting numbers (1, 2, 3, 4, 5 and so on) greater than zero. Negative integers are their counterparts (-1, -2, -3, -4, -5 and so on) less than zero.
