Answer:
115
Step-by-step explanation:
<span>(4x^3/16x^5)^1/2
= ((4/16) * x^(3-5))^1/2
= ((1/4) * x^-2 ) ^1/2
= 1/ 2x</span>
Answer:
45
Step-by-step explanation:
15*3=45
To answer this question, you have to find the least common multiple of 5, 2, and 7.
1) Find the prime factorization of each of the numbers=5, 2, 7
2) Multiply the numbers: 5*2*7=70
3) Every 70 days he will do all three things on the same day
Answer:
9b /a^5/2
Step-by-step explanation:
9√(a^-5 b^2)
9 sqrt( a^ -5 b^2)
Rewriting sqrt as ^1/2
9 ( a^ -5 b^2)^1/2
9 ( a^ -5) ^1/2 ( b^2)^1/2
we know that an exponent to an exponent means multiply
9 a^ (-5*1/2) b^(2*1/2)
9 a^-5/2 b^1
9b a^ -5/2
We know that x^-y = 1/x^y
9b /a^5/2
