The expressions 4(4^2)(8*2) and 4^5 are equivalent.

Show how the two expressions are equivalent. Describe the steps that can be applied to 4(4^2)(8*2) to create two equivalent expression 4^5

Step-by-step explanation:

First note, we can write the product 8*2 as power of 4

with substitution we get

and simplifying, using properties of exponents we get

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.

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.
