The denary, or base 10, equivalent of 22 expressed as a number is 4.
A decimal is a way of representing a number in base 10. 5280 is already expressed in base 10 and so the answer is 5280 feet!
It is a number expressed in "standard form".
Numbers expressed using exponents are called powers. When writing a number expressed as an exponent, the number is called the base.
It is: 7.0*10-9 when in scientific notation
The denary, or base 10, equivalent of 22 expressed as a number is 4.
It is only true in the sense that any numeric base, expressed in that base, is represented with the symbol "10". Confusing? Let's clarify that. Hexadecimal numbers use sixteen as the base. But how do you express the value sixteen in hexadecimal? Quite easy, it would be written as "10". The same is true in any other base. For example, in binary (base two), the value two is expressed as "10". In octal (base eight), the value eight is expressed as "10". In decimal (our familiar base ten), the value ten is expressed as "10". No matter what base you work in, the base itself will always be expressed as "10". That however is not the same thing as saying that hexadecimal numbers are based on the number ten. That is incorrect. Hexadecimal numbers use the base sixteen.

It is the value of a number which is expressed in base 16 rather than the "normal" decimal, or base 10, form.

Numbers expressed using exponents are called powers. When writing a number expressed as an exponent, the number is called the base. For example, in 23 two is the base.

Some are, some are not. Binary is just a way of writing a number. It will still be divisible be the same numbers it was divisible by in base 10.
The number 5.32 x 10 3 is expressed as: 5,320
10 is a rational number because it can be expressed as a fraction
Numbers expressed using exponents are called powers. When writing a number expressed as an exponent, the number is called the base.
An irrational number is one that can NOT be expressed as a fraction, with integer numerator and denominator. 3.8 CAN be expressed as such, namely, 38/10, so it is RATIONAL.
