Bas_tet [7]
The GCF of the first two terms: 5h²
The GCF of the last two terms: 4

5h³ and 20h² 

Both of these terms are divisible by 5. (constant)
Both of these terms also have at least 2 h's. (variable)

4h and 16

Both of these terms are divisible by 4.

Use the prime decomposition of integers to express the listed radical in its minimal expression. Do not use decimals.
kirza4 [7]

Answer:

(A) 210\sqrt{5

(B) 210\sqrt{14}

(C) 1980\sqrt{33}

(D) 37\sqrt{5}

Step-by-step explanation:

\sqrt{220500} = \sqrt{2^2*3^2*5^2*7^2*5} = 2*3*5*7\sqrt{5} =210\sqrt{5

3\sqrt{68600} = \sqrt{2^2*2*5^2*7^2*7} = 3*2*5*7\sqrt{14} =210\sqrt{14}

3\sqrt{3267}\sqrt{4400} = 3\sqrt{3^2*3*11^2}\sqrt{2^2*2^2*5^2~11} = 3*3*11\sqrt{3}*2*2*5\sqrt{11} =1980\sqrt{33}

\sqrt{1125} + \sqrt{2420} = \sqrt{3^2*5^2*5} + \sqrt{2^2*11^2*5} = 3*5\sqrt{5} + 2*11\sqrt{5} =15\sqrt{5} + 22\sqrt{5} = 37\sqrt{5}

5 (w – 21)(w + 21)<br> Simplify the equation
Serjik [45]

Answer:5w^2 -2205

Step-by-step explanation:

simplify the product so (1) w mutiplied by w gives you w^2 . (2) 21 mutilplied by 21 gives you 441 . so now you would have 5( w^2 -441 ) (3) now you distribute 5 among the numbers so you should have 5w^2 -2205 .
