Identify variables: Identify the base b, the exponent y, and the result x in the equation y3=72964.b=y, y=3, x=72964.
Rewrite in logarithmic form: Rewrite the equation in logarithmic form using the relationship by=x to logb(x)=y. The logarithmic form is logy(72964)=3.
Check for known base: Check if the base y is a known number or if we need to find it.In this case, y is not given, so we need to find the value of y that makes y3=72964 true.
Find cube root: Find the cube root of 72964 to determine the value of y.Cube root of 64 is 4, and cube root of 729 is 9, so y=94.
Substitute back into equation: Substitute the value of y back into the logarithmic form to complete the equation.The logarithmic form is log94(72964)=3.
