<u>Answer:</u> 504

<u>Step-by-step explanation: </u>

Least Common Multiple is :

             504

Calculate Least Common Multiple for :

   18, 24 and 56

Factorize of the above numbers :

   18 = 2 • 32

   24 = 23 • 3

   56 = 23 • 7

Build a prime factors table

   Number of times each prime factor

   appears in the factorization of :

Prime

Factor   Number

18   Number

24   Number

Show why the following statement is true:<br> 2^−1/2 = 1/2^1/2
Alik [6]

In order to solve a negative exponent, you have to consider the multiplicative inverse of the base:

a^{-m}=\dfrac{1}{a^m}=\left(\dfrac{1}{a}\right)^m

So, if we solve the negative exponent on the left hand side, we have

2^{-\frac{1}{2}}=\dfrac{1}{2^\frac{1}{2}}=\left(\dfrac{1}{2}\right)^{\frac{1}{2}}

which is the right hand side.

1. Robbie opens an account at a local bank and deposits $100 every week into the account.
user100 [1]

Answer:

the amount in the account after  three years?​ = $110.96

Step-by-step explanation:

the formula to calculate the amount compounded after 3year =

A = P(1 + r/n)∧nt

A =P(1 + r/n)^{nt}

where P = principal =starting amount = $100 weekly

    r= interest rate = 2.4% weekly = 0.024

    t = time interest is computed = 3years =

    n = number of time interest is compounded per year =52.1weeks

inputing the parameters

A =100(1 +  0.024/52.1)^{52.1 *3}

A = 100 (1.0005)^{208}

A = 100 *1.1096

A = $110.96
