\bf (x^2y^8)^{\frac{2}{3}}\implies \left( x^{2\cdot \frac{2}{3}}y^{8\cdot \frac{2}{3}} \right)\implies x^{\frac{4}{3}}y^{\frac{16}{3}}\implies x^{\frac{3}{3}+\frac{1}{3}}y^{\frac{15}{3}+\frac{1}{3}}\implies x^{1+\frac{1}{3}}y^{5+\frac{1}{3}} \\\\\\ x^1\cdot x^{\frac{1}{3}}\cdot y^5\cdot y^{\frac{1}{3}}\implies x^1\cdot y^5\cdot x^{\frac{1}{3}}\cdot y^{\frac{1}{3}}\implies xy^5\sqrt[3]{x}\sqrt[3]{y}\implies xy^5 \sqrt[3]{xy}

18. Curry powder is sold at $7.45 per 100 g. How much money will Thuy need in order to buy 3 kg of curry powder?
MissTica

Answer:

Step-by-step explanation:

$7.45 = 100g

x = 3kg( 3 × 1000) = 3000g

∵ $7.45 = 100g

   x        = 3000g

(100 × x) = (7.45 ×  3000)

100x = 22350

100x/100 = 22350/100

x  = $223.5

How much less would a 23-year-old female pay for a $25,000 policy of 20 year life insurance (@ $2.90 per $1000) than straight li
mojhsa [17]

<u>Answer</u>:

The female would pay  $322.00 less for a policy of $25,000

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

Since we have given that

Amount for policy = $25000

If she opt for 20 year life insurance at $2.90 per $1000.

so, her amount of premium becomes

25000\times \frac{2.9}{1000}

=$72.50

If she opt for straight life insurance at $15.78 per $1000,

Then, her amount of premium becomes

25000 \times \frac{15.78}{1000}

= $394.50

Difference between them is given by

$394.50-$72.5 = $322.00
