Answer:

2.559 * 10^1

Step-by-step explanation:

Rules of scientific notation (that I always remember)

- the number must be between 1 and 9

- if number gets smaller, exponent gets bigger; if number gets bigger, exponents gets smaller

25.59 is bigger than 9 so we move the decimal one place value to the left

and the number gets smaller meaning the exponent increases

Find the product. -8x5y2 · 6x2y

katrin [286]

Answer:

The product of the given expression $-8x^5y^2\times 6x^ 2y$ = 72x^6y^3[/tex]

Step-by-step explanation:

Given expression is $-8x^5y^2\times 6x^2y$

To find the product of the given expression:

The product of the given expression can be written as

$-8x^5 y^2\times 6x 2y=(-8x^5y^2)(6x^2y)$

$=(-8x^5y^2)(6x^2y)$

$=-48(x^5\times x^2)(y^2\times y^1)$ [since $a^m\times a^n=a^{m+n}$ ]

$=-48x^7y^3$

Therefore the product of the given expression $-8x^5y^2\times 6x^2y$ is $-48x^7y^3$

Therefore, $-8x^5y^2\times 6x^2y$ =-48x^7y^3[/tex]

The sales price of an LCD TV is $280, representing 30% off the regular price. What is the original price?

musickatia [10]

Answer:

$400

Step-by-step explanation:

Let 'p' represent the original price, the 'p-0.3p' represents the sale price:

280 = p - 0.3p .

Solving for 'p' we have p=400.

The original price of the television was $400
