WebbExponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner. For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as 3 4, where 4 is the exponent and 3 is the base. The whole expression 3 4 is said to be power. Also learn the laws of exponents here. WebbExample 1: reciprocal of a whole number. Find the reciprocal of 7.

Negative exponents review (article) Khan Academy

WebbLearn how to rewrite expressions with negative exponents as fractions with positive exponents. A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ. For example, 2⁻⁴ = 1 / (2⁴) = 1/16 ... WebbThis video explains what a reciprocal of a whole number is and what a reciprocal of a reciprocal is. Practice questions at the end of the video. Skip to: 00:... WebbSo 3/5 divided by 1/2 as an improper fraction is 6/5. Now, they want us to write it as at mixed number. So we divide the 5 into the 6, figure out how many times it goes. That'll be the whole number part of the mixed number. And then whatever's left over will be the remaining numerator over 5. harvey f lodish
