Which expression is equivalent to ?

mamaluj [8]

Answer:

Step-by-step explanation:

$\frac{(a^{2}b^{4}c)^{2}*(6a^{3}b)*(2c^{5})^{3}}{4a^{6}b^{12}c{^3}}\\\\=\frac{a^{2*2}b^{4*2}c^{2}6a^{3}b2^{3}c^{5*3}}{4a^{6}b^{12}c{^3}}\\\\=\frac{a^{4}b^{8}c^{2}6a^{3}b8c^{15}}{4a^{6}b^{12}c{^3}}\\\\=\frac{6*8*a^{4+3}b^{8+1}c^{2+15}}{4a^{6}b^{12}c{^3}}\\\\=\frac{6*2*a^{7}b^{9}c^{17}}{a^{6}b^{12}c{^3}}\\\\=\frac{12a^{7-6}c{17-3}}{b^{12-9}}\\\\=\frac{12a^{1}c^{14}}{b^{3}}\\\\=\frac{12ac^{14}}{b^{3}}$

Hint:

$x^{m}*x^{n}=x^{m+n}\\\frac{x^{m}}{x^{n}}=x^{m-n},m>n\\\frac{x^{m}}{x^{n}}=\frac{1}{x^{n-m}},n>m$

Joe works for a charity. Each year the charity gives money to different projects. The charity has a total of eight thousand nine

baherus [9]

Answer:

$Each =\pounds 1121$

Step-by-step explanation:

See comment for complete question.

Given

$Total = \pounds 8968$

$Projects = 8$

Required

Determine the amount allotted to each

From the question, we understand that each project gets each allocation.

So, the amount of each is:

$Each =\frac{Total}{Projects}$

$Each =\frac{\pounds 8968}{8}$

$Each =\pounds 1121$

<em>Each project gets £1121</em>
