- What is the answer of 20 to the power of 2? - Cuemath
We have given, 20 to the power of 2 We know that the rules for exponentiation state that if x is a positive integer and y is any real number, then y x can be represented as: y x = y × y × … × y (x times) Hence, 20 to the power of 2 can be written as 20 2 Where 2 is the power, whereas 20 is called the base of an expression

For example, 2 and 5 are the prime factors of 20, i e , 2 × 2 × 5 = 20 We know that the factors of a number are the numbers that are multiplied to get the original number For example, 4 and 5 are the factors of 20, i e , 4 × 5 = 20 Therefore, it should be noted that all the factors of a number may not necessarily be prime factors
- a^2 + b^2 Formula | A Square + B Square Formula - Cuemath
(a + b) 2 = a 2 + b 2 + 2ab Let us substitute the value of a and b as x and y (x + y) 2 = x 2 + y 2 + 2xy On subtracting 2xy from both the sides, x 2 + y 2 = (x + y) 2 - 2xy Answer: Hence verified Example 3: Find the sum of the squares of 10 and 20 directly and use the a^2 + b^2 formula

Since the cubes of even numbers are always even Therefore, the value of cubes of numbers 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 will be even Using the Cubes 1 to 20 Chart, Find the Value of 2 Plus 7 Cube plus 1 The value of 7 3 is 343 So, 2 + 7 3 + 1 = 2 + 343 + 1 = 346 Hence, the value of 2 plus 7 cube plus 1 is 346
- What is the value of 2 to the power of 20? - Cuemath
Given, 2 to the power of 20 Basically, the rules for exponents states that if p is a positive integer and m is any real number, then p m can be represented as: p m = p × p × … × m (m times) Hence, 2 to the power of 20 can be written as 2 20 Here, the number 2 is called the base, whereas 20 is the power or exponent of the expression
- Learn Table of 20 | Multiplication Table of Twenty - Cuemath
To obtain the multiplication table of 20, we need to multiply 20 with natural numbers Multiplication table of 20 is nothing but repeated addition We know that 20 x 1 = 20 If we add 20 to this number, we get the next multiple Similarly, if we keep adding 20 to the next multiples, we get the table of 20
