CPM Homework Help : PC Problem 3-126

In Algebra 2 you learned a fast way to solve equations of the form $x^{1.05} = 2$ by raising each side to a well-chosen power. We’ll review that method now. Copy and complete the steps below.

Given equation	$x^{1.05} = 2$
(Raise both sides to the reciprocal of the exponent of the variable)	$(x^{1.05})^{\frac{1}{1.05}}=$ ____
(Power Law for exponents)	$x^{1} =$ ____
Use a calculator to evaluate (rounded to nearest $0.001$ )	$x = 1.935$

The key steps to remember are in bold. Copy this solution into your Tool Kit.
