Negative exponents fractions11/25/2023 Please click "Solve Similar" for more such examples.ĮXAMPLE Simplify (x^-3y^2z^-2)/(x^2y^-4z^-3) and write the answer with positive exponents. Let's see how our math solver simplifies this problem and other similar problems. ![]() a^-n+b^-n= 1/a^n+1/b^n= (b^n+a^n)/(a^(n)b^n)ĮXAMPLE Express xy^-2 with positive exponents.ĮXAMPLE Multiply x^-1y^-3 and (x^2y^-2) and write the answer with positive exponents. Remarks Theorems 1-5 on page 320 are true when a>0, b>0, and m,n are rational numbers.ħ. ![]() , it can be shown that the theorems for exponents are still valid. it can be shown that the previous theorems for exponents are valid when a zero exponent occurs.Īgain, for the first and third parts of Theorem 4 for exponents lu be consistent, we must have, when m=0 and a!=0,Īccording to the definition of negative exponents, a!=0, a^-n=1/a^n When a=0, we have 0^0, which is indeterminate.Īccording lo this definition. The following are direct applications of the theorems:ģ. Hence (3x^(1/2)-2)(x^(1/2)+3)= 3x+7x^(1/2)-6Īccording to the definition, Theorems 4 and 5 are valid when a>0, b>0, and m,n are positive fractional exponents. Click on "Solve Similar" button to see more examples. Let’s see how our step by step solver solve this and similar problems. Note When a,b ∈ R, a>0, b>0, and p,q,r,s,u,v ∈ N, we have The following are direct applications of the theoremsĦ. Hence the literal numbers may not be assigned negative specific values. Note Theorems 1-3 are true for positive fractional exponents when a and b are positive numbers. and m,n are positive fractional exponents. When n is an even number and a0, a^(1/n)>0. When a,b ∈ R, a!=0, b!=0, and m,n ∈ N ,we have the following theorems from Chapter 3 The purpose of this chapter is to extend the scope of the rules of exponents, discussed in Chapter 3, and to study some of their applications in algebra.
