Answer:..Step-by-step explanation:
Answer:
GCF= 1
LCM= 1680
Step-by-step explanation:
GCF= Find the prime factorization of 21, 21 = 3 x 7
Find the prime factorization of 80, 80 = 2 x 2 x 2 x 2 x 5
Then multiply the prime factors both numbers have in common
LCM= multiply the two numbers together and ignore all negative signs
2 hours = 45 pages
1 hour = 45 ÷ 2 = 22.5 pages
12 hours = 22.5 x 12 = 270 pages
Answer; 270 pages
<span>First we need to find the GCF (greatest common factor)</span>
<span>Factors of 42 are:
1, 2, 3, 6, 7, 14, 21, 42</span>
<span>Factors of 48 are:
1, 2, 3, 4, 6, 8, 12, 16, 24, 48</span>
<span>GCF is 6</span>
<span>To simplify you divide numerator and denominator into the GCF</span>
<span>42 ÷ 6 = 7</span>
<span>48 ÷ 6 = 8</span>
<span>42/48 = 7/8</span>
<span>Hope this helps. :)

Answer:
![\sqrt[5]{a^{3} b^{2}c}](https://tex.z-dn.net/?f=%20%20%5Csqrt%5B5%5D%7Ba%5E%7B3%7D%20b%5E%7B2%7Dc%7D)
Step-by-step explanation:
Rationalization factor of ![\sqrt[5]{a^2 b^3 c^4}](https://tex.z-dn.net/?f=%20%20%5Csqrt%5B5%5D%7Ba%5E2%20b%5E3%20c%5E4%7D%20)
![= \sqrt[5]{a^{5-2} b^{5-3}c^{5-4}}\\= \sqrt[5]{a^{3} b^{2}c^{1}}\\= \sqrt[5]{a^{3} b^{2}c}\\](https://tex.z-dn.net/?f=%20%3D%20%5Csqrt%5B5%5D%7Ba%5E%7B5-2%7D%20b%5E%7B5-3%7Dc%5E%7B5-4%7D%7D%5C%5C%3C%2Fp%3E%3Cp%3E%3D%20%5Csqrt%5B5%5D%7Ba%5E%7B3%7D%20b%5E%7B2%7Dc%5E%7B1%7D%7D%5C%5C%3C%2Fp%3E%3Cp%3E%3D%20%5Csqrt%5B5%5D%7Ba%5E%7B3%7D%20b%5E%7B2%7Dc%7D%5C%5C%20)
