Answer:
A. 5^20 x 7^40
Step-by-step explanation:
The exponent outside applies to each factor inside parentheses. The rules of exponents say ...
(a^b)^c = a^(b·c)
so, you have ...
![(5^2\times 7^4)^{10}=5^{2\cdot 10}\times 7^{4\cdot 10}=5^{20}\times 7^{40}](https://tex.z-dn.net/?f=%285%5E2%5Ctimes%207%5E4%29%5E%7B10%7D%3D5%5E%7B2%5Ccdot%2010%7D%5Ctimes%207%5E%7B4%5Ccdot%2010%7D%3D5%5E%7B20%7D%5Ctimes%207%5E%7B40%7D)
Answer:
Step-by-step explanation:
The percent increase formula is
![%increase=\frac{new-original}{original}*100%](https://tex.z-dn.net/?f=%25increase%3D%5Cfrac%7Bnew-original%7D%7Boriginal%7D%2A100%25)
For the bread, our percent increase looks like this:
![\frac{25-15}{15}*100](https://tex.z-dn.net/?f=%5Cfrac%7B25-15%7D%7B15%7D%2A100)
which gives us a percent increase of 66.7%
For the cakes, our percent increase looks like this:
![\frac{12-10}{10}*100](https://tex.z-dn.net/?f=%5Cfrac%7B12-10%7D%7B10%7D%2A100)
which gives us a percent increase of 20%
GCF of 21, 49, 35 is 7
Step-by-step explanation:
GCF is the greatest common factor
- The factors of a number are the numbers you multiply to get the number
- The GCF of some numbers is the greatest common factor of the common factors of the numbers
- Ex: the greatest common factor of 4, 6, and 10 is 2, because the factors of 4 are 1, 2, 4, the factors of 6 are 1, 2, 3, 6, and the factors of 10 are 1, 2, 5, 10, the common factors are 1 and 2, the greatest is 2
∵ 21 = 1 × 21, 3 × 7
∴ The factors of 21 are 1, 3, 7, 21
∵ 49 = 1 × 49, 7 × 7
∴ The factors of 49 are 1, 7, 49
∵ 35 = 1 × 35, 5 × 7
∴ The factors of 35 are 1, 5, 7, 35
Lets find the common factors of the three numbers
∵ The common factors are 1 and 7
∵ The greatest is 7
∴ The greatest common factor of 21, 49, 35 is 7
GCF of 21, 49, 35 is 7
