Explain how to multiply square roots

When multiplying square roots, we simply multiply the values inside the square roots. So for example, let's look at the problem below.

√a · √a

So the square root of a times the square root of a equals the square root of a time a or √a² and the square root of a² is simply a.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
