What is the index of the radical below? 4 radical 8

well.... If The index of a radical is a number which indicates which root is desired of the number under the radical. For instance, 83 has an index of 3, and means “the cube root of 8”. has an index of 4, and means “the 4th root of 16”. When working with radicals, can the radicand be negative when the index is odd?

hope you this helps

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

=240

=48
