What does 10 to the negative 2 power mean?
What does 10 to the negative 2 power mean?
Given, 10 to the power of negative 2. Basically, any negative exponent represents that how many times the reciprocal of the base can be multiplied. For example, a-n = 1/an = (1/a) × (1/a) × … × 1/a (n times) Hence,10 to the power of negative 2 can be written as 10-2.
What is a negative 2 squared?
“This is because to square a number just means to multiply it by itself. For example, (−2) squared is (−2)(−2)=4. Note that this is positive because when you multiply two negative numbers you get a positive result.” – This, of course, is the exact opposite of what was asked, but it’s the given response.
What does a negative 2 exponent mean?
A negative exponent just means that the base is on the wrong side of the fraction line, so you need to flip the base to the other side. For instance, “x–2” (pronounced as “ecks to the minus two”) just means “x2, but underneath, as in 1 x 2 \frac{1}{x^2} x21 “.
What does 2 to the power of negative 2 mean?
A negative exponent is defined as the multiplicative inverse of the base, raised to the power which is opposite to the given power. In simple words, we write the reciprocal of the number and then solve it like positive exponents. For example, (2/3)-2 can be written as (3/2)2.

What is 3rd to the 2nd power?
Explanation: 3 to the second power can be written as 32 = 3 × 3, as 3 is multiplied by itself 2 times. Here, 3 is called the “base” and 2 is called the “exponent” or “power.” In general, xn means that x is multiplied by itself for n times. 3 × 3 = 32 = 9.
