Given Equation: We are given the equation 3a=532. To solve for a, we need to express both sides of the equation with the same base and then compare the exponents.
Express with Same Base: The fifth root of 32 can be written as (32)1/5. This uses the property that the nth root of a number is the same as raising that number to the power of 1/n.
Simplify Right Side: Now we have 3a=(32)1/5. Using the property of exponents that (xm)n=xm∗n, we can simplify the right side of the equation.
Set Exponents Equal: Simplify the right side: (32)51=32⋅51=352.
Set Exponents Equal: Simplify the right side: (32)1/5=32∗1/5=32/5.Now we have 3a=32/5. Since the bases are the same, we can set the exponents equal to each other to find the value of a.
Set Exponents Equal: Simplify the right side: (32)51=32∗51=352.Now we have 3a=352. Since the bases are the same, we can set the exponents equal to each other to find the value of a.Set the exponents equal: a=52.
