What Is 2 The 4th Power?

How do you write 2 to the 5th power?

Applying Powers with Superscript For example, to write “2 raised to the 5th power,” type “25” with no space between the numbers.

Highlight just the “5” and press “Control-Shift-Equals” or click the superscript icon on the “Home” tab, which looks like an “x squared.” The “5” will shrink and shift upward..

What does the exponent 4 mean?

How do you know if a number is a power of 10?

double x_log10 = log10(x_d); // Check if result is integer number – has zero fractional part. If we want to operate on integer numbers only, we may come up with a recursive algorithm that checks whether the number is greater than zero, divisible by 10 and then calls the same function for x/10.

How do you tell if a number is a power of 2?

How can you tell if a number is a power of two? That’s easy if it’s in the form 2n, where n is an integer. For example, 212, 20, and 2-37 are powers of two….For example, 16,392 is not a power of two because it returns an odd quotient after three divisions:16,392/2 = 8,196.8,196/2 = 4,098.4,098/2 = 2,049.

What does 4 mean in math?

factorialmeans factorial. It means any number factorial is product of back counted numbers till 1. Hence,4! means 4×3×2×1 i.e. 24.

What is equivalent to 4 to the power of 3?

The phrases 3 to the 4th power and 3 to the power of 4 are equivalent to the algebraic operations 4 × 4 × 4 × 4 and 44.

What is the power of 10?

A power of 10 is as many number 10s as indicated by the exponent multiplied together. Thus, shown in long form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0; for example, 106 is written 1,000,000.

What is 2 to the power?

Computer science. Two to the power of n, written as 2n, is the number of ways the bits in a binary word of length n can be arranged. A word, interpreted as an unsigned integer, can represent values from 0 (000…0002) to 2n − 1 (111… 1112) inclusively.

What is the answer to to the 4th power?

In arithmetic and algebra, the fourth power of a number n is the result of multiplying four instances of n together. So: n4 = n × n × n × n.

What is 2 the 5th power?

Exponents are numbers that tell you how many times to use the number in multiplication. If a number is said to be to the ‘5th power,’ this means the exponent for that number is 5, and you would multiply that number by itself five times.

What does 4 to the power of 4 mean?

Answer and Explanation: When a number is said to be ‘to the fourth power,’ that just means that you need to multiply the number by itself four times. For example, 7 to the…

How do you know if a number is a power of 4?

A simple method is to take log of the given number on base 4, and if we get an integer then number is power of 4. 2. Another solution is to keep dividing the number by 4, i.e, do n = n/4 iteratively. In any iteration, if n%4 becomes non-zero and n is not 1 then n is not a power of 4, otherwise n is a power of 4.

How do you know if a number is a power of 3?

So the following is a fast test:Find the binary logarithm of n by finding the position of the leading 1 bit in the number. … Look up the potential power of three in a table indexed by this position and compare to n (if there is no power of three you can store any number with a different binary logarithm).More items…•
