Simplify the expression. 12x^-6 y^10 times 3x^7 y

Vlada [557]

We need to simplify the expression:

$12x^{-6}y^{10} \times (3x^{7}y)$

Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:

Now,

$12x^{-6}y^{10} \times 3x^{7}y=(12 \times 3)\times (x^{-6}\times x^{7})\times (y^{10}\times y)$

On simplifying the above expression we get:

$36\times x^{(-6+7)}\times y^{(10+1)}$

$=36 \times x^{1}\times y^{11}$

$=36 \times x \times y^{11}$

$=36xy^{11}$

So the simplified form of the expression $12x^{-6}y^{10} \times 3x^{7}y=36xy^{11}$ .

A fish tank that is 5 feet long by 3 feet wide by 3 feet high has a 2 foot cubic stone placed in the bottom how much water will

maks197457 [2]

Answer:

37ft³

Step-by-step explanation:

Volume of the fish tank = length × width × height = 5ft × 3ft × 3ft = 45ft³

Volume of the cubic stone = length × length × length = (2ft)³ = 8ft³

Volume of the water = volume of the fish tank - volume of the cubic stone

i.e Volume of the water = 45ft³ - 8ft³ = 37ft³
