Answer:

see explanation

Step-by-step explanation:

$\sqrt[3]{27}$ = 3

Since 3 × 3 × 3 = 27

$\sqrt{25}$ = ± 5

Since 5 × 5 = 25 and - 5 × - 5 = 25

$\sqrt{81}$ = ± 9

Since 9 × 9 = 81 and - 9 × - 9 = 81

$\sqrt[3]{1}$ = 1

Since 1 × 1 × 1 = 1

Answer:

Part 1) $x=-0.07$

Part 2) $y=2.48$

Step-by-step explanation:

Part 1) we have

$15^{-9x} =6$

Solve for x

Apply log both sides

$log(15^{-9x})=log(6)$

$-x*(9log(15))=log(6)$

$x=-log(6)/(9log(15))$

$x=-0.07$

Part 2) we have

$e^{y}=12$

Apply ln both sides

$ln(e^{y})=ln(12)$

$y*ln(e)=ln(12)$

Remember that

$ln(e)=1$

$y=ln(12)$

$y=2.48$

rjkz [21]

Answer:

The area of the sheet is approximately 50.59 m² or 50.6 m²

Step-by-step explanation:

The area of a rectangle is given by the following expression:

$area = width*height$

Since breadth is the same as the width of the sheet, we can calculate its area as shown below:

$area = 9.96*5.08 = 50.59$

The area of the sheet is approximately 50.59 m² or 50.6 m²
