Answer:
£17.20
Step-by-step explanation:
A clothes shop has some special offers. ?
The normal price of a T-shirt is £7.40 The normal price of a jumper is £9.80.
T-shirts are buy one get one free Jumpers are 3 for 2.
How much does it cost to get 5 jumpers and 2 T-shirts using this offer as appropriate?
The cost of 2 T-shirts since it is a buy 1 get 1 free => £7.40
The cost of 5 jumpers =
You buy 3 Jumpers ,you get 2 jumpers free => £9.80
The total cost = £7.40 + £9.80
= £17.20
Answer:
![\frac{4\sqrt{5} }{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%5Csqrt%7B5%7D%20%7D%7B5%7D)
Step-by-step explanation:
![\frac{4\sqrt{6} }{\sqrt{30} } =\frac{\sqrt{30} *4*\sqrt{6} } \sqrt{30} {\sqrt{30} } \\\\](https://tex.z-dn.net/?f=%5Cfrac%7B4%5Csqrt%7B6%7D%20%7D%7B%5Csqrt%7B30%7D%20%7D%20%3D%5Cfrac%7B%5Csqrt%7B30%7D%20%2A4%2A%5Csqrt%7B6%7D%20%7D%20%5Csqrt%7B30%7D%20%7B%5Csqrt%7B30%7D%20%7D%20%5C%5C%5C%5C)
![\frac{4\sqrt{6*30} }{30} =\frac{4*\sqrt{180} }{30} =\frac{4*\sqrt{36*5} }{30} = \\\\\frac{4*6\sqrt{5} }{6*5} =\frac{4\sqrt{5} }{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%5Csqrt%7B6%2A30%7D%20%7D%7B30%7D%20%3D%5Cfrac%7B4%2A%5Csqrt%7B180%7D%20%7D%7B30%7D%20%3D%5Cfrac%7B4%2A%5Csqrt%7B36%2A5%7D%20%7D%7B30%7D%20%3D%20%5C%5C%5C%5C%5Cfrac%7B4%2A6%5Csqrt%7B5%7D%20%7D%7B6%2A5%7D%20%3D%5Cfrac%7B4%5Csqrt%7B5%7D%20%7D%7B5%7D)
The Power of a Product property tells us that when you multiply two numbers with the same base, you can add their exponents to determine the product.
For example,
![x^{a}](https://tex.z-dn.net/?f=%20x%5E%7Ba%7D%20)
*
![x^{b}](https://tex.z-dn.net/?f=%20x%5E%7Bb%7D%20)
=
![x^{a+b}](https://tex.z-dn.net/?f=%20x%5E%7Ba%2Bb%7D%20)
.
The Power of a Quotient Property tells us that when you divide two numbers with the same base, you can subtract their exponents to determine the quotient.
For example,
![x^{a}](https://tex.z-dn.net/?f=%20x%5E%7Ba%7D%20)
/
![x^{b}](https://tex.z-dn.net/?f=%20x%5E%7Bb%7D%20)
