Answer:

$618.95 rounded up. 0.004c

£388.09 on rent and $230.84 food

We can round up and state $619 to nearest tenth.

Or leave as non rounded Total $618.93

Step-by-step explanation:

27% of 1,437.40=388.09

1,437.40 - 388.09 = 1049.31

22% of 1049.31 = 230.8482

$230,84 Shown here, as not round up or down as 230.84 as £388.09 was not rounded up from 388.098.

= $618.95 rounded up. 0.004c

Which expression is equivalent to (4^5/4 4^1/4/4^1/2) ^1/2

Lilit [14]

The expression is equivalent to 2 , Option C is the correct answer.

<h3>What is an Expression ?</h3>

An expression is a mathematical statement consisting of variables , constants and mathematical operators.

The expression given in the question is

$\rm( {\dfrac{4^{5/4} * 4^{1/4}}{4^{1/2}}})^{1/2}$

By exponent rule

$\rm a^m * a^n = a^{m+n}\\\\a^m \div a^n = a^{m-n}$

Here so ,

$\rm 4^{(\dfrac{5}{4} +\dfrac{1}{4} -\dfrac{1}{2})^{1/2}$

$\rm 4^{(\dfrac{6}{4} -\dfrac{1}{2})^{1/2}\\\\ \\\\\\\\\\\\\\\\\\\\\\\\\\\\$

$4^{(\dfrac{6-2}{4} )^{1/2}\\$

$4^{1/2}\\\\(2^2)^{1/2}\\\\2$

Therefore the expression is equivalent to 2 , Option C is the correct answer.
