Question

(- 49x³y⁵) ÷ (35xy²)​

Answer 1

Answer:

EXAMPLE

Calculation of an expression when substitutes of various mathematical symbols are provided

In this type of questions, the substitutes for various mathematical symbols ( +, - , X, /, >, < , = ) are provided in the form of letters or numbers or special characters or the operators themselves (their meaning is redefined as given in the question) and then we have to evaluate the value of the given expression using these operators and their defined meanings.

For e.g,

If '+' means 'divided by', '-' means 'multiplied', 'X' means 'plus' and '/' means 'minus' then ( 280 + 10 X 20 ) - 8 / 6 = ?

Substituting the operators by their meaning as given in the question, we have

(280/10 + 20) X 8 - 6 = (28+ 20) X 8 - 6 = 48 X 8 - 6 = 378.

Answer 2

Answer:

$-14x^{2}y^{3}$

Step-by-step explanation:

$x^{a}\\-\\x^{b}$ = x^a-b

so,

-49-(+35)

$x^{3} - x ^{-1}$

$y^{5}- y^{-2}$

$-14x^{2}y^{3}$
