Answer:

Answer is below.

Step-by-step explanation:

6^2*6^-2=1 is the same as saying 6^2*1/6^2, which is just equal to one. This applies as negative exponents are expressed as fractions.

5^3 * 5^-3 is equal to 1 as the law of exponents states that if the base is the same, the numbers multiplied is the base to the power of the sum of the previous exponents. Therefore 5^3-3=5^0 and because anything to the power of 0 (except 0) is equal to 1, the answer is 1.

The formula sa

sergeinik [125]

Answer:

The correct option is (b).

Step-by-step explanation:

The formula for the side of a cube of surface area SA is as follows :

$s=\sqrt{\dfrac{SA}{6}}$

When SA = 180 m²

$s=\sqrt{\dfrac{180}{6}}\\\\s=\sqrt{30}$

When SA = 120 m²

$s=\sqrt{\dfrac{120}{6}}\\\\s=\sqrt{20}\\\\=2\sqrt5$

Difference,

$=30-2\sqrt5$

So, the correct option is (b).
