WebFor exponents with the same base, we can add the exponents: a -n ⋅ a -m = a -(n+m) = 1 / a n+m Example: 2 -3 ⋅ 2 -4 = 2 - (3+4) = 2 -7 = 1 / 2 7 = 1 / (2⋅2⋅2⋅2⋅2⋅2⋅2) = 1 / 128 = 0.0078125 When the bases are diffenrent and the exponents of a and b are the same, we can multiply a and b first: a -n ⋅ b -n = ( a ⋅ b) -n Example: WebAn exponent (such as the 2 in x2) says how many times to use the variable in a multiplication. Example: y2 = yy ( yy means y multiplied by y, because in Algebra putting …

WebOct 9, 2024 · 1. Know the order of operations. When simplifying math expressions, you can't simply proceed from left to right, multiplying, adding, subtracting, and so on as you go. Some math operations take precedence over others and must be done first. In fact, doing operations out of order can give you the wrong answer. 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. … north kyo

WebSimplify the exponential expression {5^0}. We have a nonzero base of 5, and an exponent of zero. The zero rule of exponent can be directly applied here. ... After we multiply the exponential expressions with the same base by adding their exponents, we arrive at having one variable with a negative exponent, and another with zero exponent. Don ... WebJun 14, 2024 · Since the base values are both four, keep them the same and then add the exponents (2 + 5) together. 4 2 × 4 5 = 47 Then multiply four by itself seven times to get the answer. 4 7 = 4 × 4 × 4 × 4 × 4 × 4 × 4 = 16,384 Let’s expand the above equation to … WebOct 24, 2024 · Remember, we're simplifying using positive exponents, so we need to change x^-4.We know from our exponent properties that x^-4 is 1 / x^4 times y^5.Well, 5 is positive, so we don't need to change it. north ks
