WebFirst, convert the negative exponents to positive exponents by taking the reciprocal of the given number. Thus, (⅔) -2 becomes (3/2) 2 and (4/2) -3 becomes (2/4) 3 Now, multiply the numbers, and we get = (3/2) 2 × (2/4) 3 = (9/4)× (8/64) Now, … Webb-n/m = 1 / bn/m = 1 / ( m√b) n The base 2 raised to the power of minus 1/2 is equal to 1 divided by the base 2 raised to the power of 1/2: 2 -1/2 = 1/2 1/2 = 1/ √2 = 0.7071 Fractions with negative exponents The base a/b raised to the power of minus n is equal to 1 divided by the base a/b raised to the power of n:
WebIf you have ANY fractional power, the denominator tells what root to take and the numerator tells what power to raise that number to. For example, 16^3/2 means take the square root of 16, then raise that to the 3rd power (getting 64 as the answer). WebIndices are used to show numbers that have been multiplied by themselves. They can be used instead of the roots such as the square root. The rules make complex calculations that involve powers easier.
WebFeb 24, 2024 · Doing Calculations with Fractions 1 Add fractions with the same denominator by combining the numerators. To add fractions, they must have the same denominator. If they do, simply add the numerators together. [2] For instance, to solve 5/9 + 1/9, just add 5 + 1, which equals 6. The answer, then, is 6/9 which can be reduced to 2/3. 2 WebJun 2, 2015 · Numbers Raised to Fractional Exponents How to solve an equation with fraction powers in your exponent Brian McLogan 1.25M subscribers Join Subscribe Save 202K views 7 years ago 👉 …
WebTo undo a square root, you raise it to the 2nd power (square it). What you do on one side you must do on the other side. So sqrt (n)^2 = n while sqrt (2n+6)^2 = 2n+6 This will leave you with n=2n+6 to solve for n.
