WebPutting it all together, the steps are as follows: ( x3 ) ( x4) = ( xxx ) ( xxxx) = xxxxxxx. = x7. Then the simplified form of (x3) (x4) is: x7. Note that x7 also equals x(3+4). This demonstrates the first basic exponent rule: Whenever you multiply two terms with the same base, you can simplify by adding the ... Websimplifying first: \left (-3x^ {-1}y^2\right)^2 (−3x−1y2)2 = \left (\dfrac {-3y^2} {x}\right)^2 = ( x−3y2)2 = \dfrac { (-3)^2 (y^2)^2} { (x)^2} = (x)2(−3)2(y2)2 = \dfrac {9 y^4} {x^2} = x29y4 squaring first: \left (-3x^ {-1}y^2\right)^2 (−3x−1y2)2 = (-3)^2 (x^ {-1})^2 (y^2)^2 = (−3)2(x−1)2(y2)2 = (9) (x^ {-2}) (y^4) = (9)(x−2)(y4)
WebTo simplify a power of a power, you multiply the exponents, keeping the base the same. For example, (23)5 =215 ( 2 3) 5 = 2 15. This leads to the Power Property for Exponents. Power Property of Exponents If x x is a real number and a,b a, b are whole numbers, then (xa)b =xa⋅b ( x a) b = x a ⋅ b To raise a power to a power, multiply the exponents. WebThis expression has two variables, a fraction, and a radical. Let us take it step-by-step and see if using fractional exponents can help us simplify it. We will start by simplifying the denominator since this is where the radical sign is located. Recall that an exponent in the denominator of a fraction can be rewritten as a negative exponent.
WebOct 9, 2024 · Solve the exponents. After tackling parentheses, next, solve your expression's exponents. This is easy to remember because, in exponents, the base number and the power are positioned right next to each other. Find the answer to each exponent problem, then substitute the answers back into your equation in place of the exponents themselves. [3]
