2016年5月16日 · How do you simplify #32^(3/5)#? Algebra Exponents and Exponential Functions Fractional Exponents. 1 Answer

2016年10月29日 · #3/5# th of the cost is #13.32#. When "translating" words to an equation, "of" means multiplication and "is" means equal. Let #x=# the cost. #3/5 x = 13.32# Multiply both sides by #5/3# #5/3 * 3/5 x = 5/3 * 13.32# #cancel5/cancel3 * cancel3/cancel5 x = (5*13.32)/3# #x=22.2#, so the cost of the present is #$22.20#.

2016年8月22日 · f(x) has zeros 1, -1/8 and 3/4 >f(x) = 32x^3-52x^2+17x+3 By the rational roots theorem, any rational zeros of f(x) are expressible in the form p/q for integers p, q with p a divisor of the constant term 3 and q a divisor of the coefficient 32 of the leading term.

2016年11月1日 · x = 11/2 = 5 1/2 = 5.5 When you have a variable in the index, you are working with an exponential equation. There are 2 types of exponential equations those that can be calculated by using known powers, and those that need to be calculated using logs and a calculator. This example is an example of the former, because both bases are powers of 2. …

Take out the greatest common factor first. =2x^3(x+2)(x-2)(x^2+4) First, find the highest number that goes into both terms in the expression (in this case 2x^3).
