Answer:

500000

Step-by-step explanation:

We need to find the value of the given expression :

5^{\dfrac{5}{2}}\times 20^{\dfrac{3}{2}}\div 10^{-2}

We can do it as per BODMAS rule.

5^{\dfrac{5}{2}}\times (\dfrac{20^{\dfrac{3}{2}}}{10^{-2}})\\\\=5^{\dfrac{5}{2}}\times {20^{\dfrac{3}{2}}}\times {10^{2}}\\\\=5^{\dfrac{5}{2}}\times {20^{\dfrac{3}{2}}}\times 100\\\\=5^{\dfrac{5}{2}}\times {(5\times 4)^{\dfrac{3}{2}}}\times 100\\\\=5^{\dfrac{5}{2}}\times {(5^{\dfrac{3}{2}})\times (4)^{\dfrac{3}{2}}}\times 100\\\\=5^{(\dfrac{5}{2}+\dfrac{3}{2})}\times 2^2^{\dfrac{3}{2}}\times 100\\\\=5^4\times 2^3\times 100\\\\=625\times 8\times 100\\\\=500000

So, the required answer is 500000.

Which is true about the polynomial –3xy2 + 5x2y?
Semmy [17]

Answer:  The answer is a cubic binomial.

Step-by-step explanation:  The given polynomial is

P(x,y) =-3xy^2+5x^2y.

We are to write the truth about the above polynomial, its type, etc.

Since the polynomial contains two expressions (terms), so it is a binomial.

Also, the degree of both the terms -3xy^2 and 5x^2y is 3.

We know that the degree of a polynomial is the highest degree among the terms that are present in the polynomial, so the degree of P(x, y) is 3.

Therefore, P(x, y) is a binomial of degree 3.

Thus, it is a cubic binomial.
