How do I simplify radicals?
Answers
Answer:
Step 1: Find the prime factorization of the number inside the radical. Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Click on the link to see some examples of Prime Factorization. Also factor any variables inside the radical.
Step 2: Determine the index of the radical. The index tells you how many of a kind you need to put together to be able to move that number or variable from inside the radical to outside the radical. For example, if the index is 2 (a square root), then you need two of a kind to move from inside the radical to outside the radical. If the index is 3 (a cube root), then you need three of a kind to move from inside the radical to outside the radical.
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. If there are nor enough numbers or variables to make a group of two, three, or whatever is needed, then leave those numbers or variables inside the radical. Notice that each group of numbers or variables gets written once when they move outside the radical because they are now one group.
Step 4: Simplify the expressions both inside and outside the radical by multiplying. Multiply all numbers and variables inside the radical together. Multiply all numbers and variables outside the radical together.
Example:
Example 1 – Simplify: Example 1
Step 1: Find the prime factorization of the number inside the radical.
252=2*2*3*3*7
Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind.
√252= √2*2*3*3*7
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical.
2*3√7
Step 4: Simplify the expressions both inside and outside the radical by multiplying.

Step-by-step explanation:
Add 28,400 and 33,900 to get 62,300 then subtract that from 93,300
Answer:
31,000
Step-by-step explanation:
28,400+33,900= 62,300.
Take the total amount of visitors (93,300) and subtract 62,300 from that.

Patty can make 10 purses in 8 hours. At this rate, how many purses can she make in 28 hours?
Answers
Answer:
35 purses
Step-by-step explanation:
Set up a proportion, where x is the number of purses she can make in 28 hours:
[tex]\frac{10}{8}[/tex] = [tex]\frac{x}{28}[/tex]
Cross multiply and solve for x:
8x = 280
x = 35
So, in 28 hours, she can make 35 purses

4 ¾ feet = 4 × 4 + 6 / 4
4 ¾ feet = 19/4 feet
1 foot = 12 inches
Then , 19/4 feet = 19/4 × 12 inches
= 19/4 × 12
= 19 × 12 / 4
= 228/4 inches
= Both the numerator and denominator are divisible by 4 .
Hence ,
= 228 ÷ 4 / 4 ÷ 4
= 57/1
= 57 inches
Therefore , a piece of ribbon which is 4 ¾ feet long in inches :

So i'm having difficulty understanding this "When multiplying the same base raised to an exponent __ the base and __ the exponents" Please help i do not understand this.
Answers
Answer:
When multiplying the same base raised to an exponent, keep the base and add the exponents.
Step-by-step explanation:
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.
I hope this helped you understand more!
