Tell me the question and I’ll help you with it is it simplify or evalute etc.
Given expression:
2x(x + 7)-(3x +1);
To distribute implies to spread a process equally in an expression. Often times, the distributive property is used for expressions inside parentheses;
2x(x + 7)-(3x +1)
Distribute 2x over the first parentheses;
the negative sign distributes over the second part
= (2x² + 14x) - 3x -1
= 2x² + 14x -3x -1
Add like terms;
= 2x² + 11x -1
This expression 2x² + 11x -1 is equal to the given one
<h3>I'll teach you how to solve (81x^-20 y^-16)^-3/4</h3>
---------------------------------------------------------------
(81x^-20 y^-16)^-3/4
Apply exponents rule:
(81x^-20 y^-16)^-3/4=
1 / (81x^-20 y^-16)^-3/4
Simplify (81x^-20 y^-16)^-3/4:
1/27/x^15 y^12
Apply the fraction rule:
x^15 y^12 / 27
Your Answer Is x^15 y^12 / 27
