Answer:
x= 20 i think sorry if it's wrong⊙﹏⊙
<h2>22</h2>
In this problem, we need to use <u>multiplication</u> and <u>subtraction</u> method to solve it.
_________________________________
x(y) means to <u>multiply</u> x with y
_________________________________
Note that {a = 7} and {b = 6}
First, we need to multiply 4 with {a = 7}, we get:
4(7) = <em>28</em>
<em />
Then, we need to subtract {b = 6} from <em>28</em>, we get:
<em>28</em> – 6 = 22
Finally, this simplifies as:
4(7) – 6 = 22
<em>Hope this helps :)</em>
Power of power rule:
Zero-Exponent Rule: a0 = 1, this says that anything raised to the zero power is 1. Power Rule (Powers to Powers): (am)n = amn, this says that to raise a power to a power you need to multiply the exponents. ... Only move the negative exponents.
Power of product rule:
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. ... Adding the exponents is just a short cut! Power Rule. The "power rule" tells us that to raise a power to a power, just multiply the exponents.
It’s important because you may doing something that includes that and you don’t have a ruler etc..
