Lol, this is pretty simple (sorry if me saying simple makes you feel stupid, if it makes you feel any better I'm rlly stupid lol). Well just look at is normally as 8+8= which would equal 16 :) I really hope this helps.

The |x| operator means 'absolute value' or the positive value of the negative values. To help this make sense, here's a visual representation:
$|-8| = 8$

But,
$|8| = 8$

Do you see what I mean? BTW, your answer will just be 8 + 8 or 16.

Solve the following exponential equation: 5^x=2 e^x=10

olya-2409 [2.1K]

Number 1.

$5^x=2$ , first we will take the $log$ of both of these numbers getting us,

$x=\frac{log(2)}{log(5)}$ , which then gives us that $x=0.4306777777....$

Number 2

$e^x=10$ , solve for our exponent, $2.718282^x=10$ , use the logarithmic formula, and we get,

$x=\frac{log(10)}{log(2.718282)}$ , which then we get that $x=2.302585$

Pemdas please help explain too please

Subtraction

(left to right)

4²-(3.1+6.4)+4.5

According to PEMDAS, we will do what is inside the parenthesis.

3.1+6.4 = 9.5

4²-9.5+4.5

Then we do figure out the exponent.

4² = (4)(4) = 16

16-9.5+4.5

Then we do subtraction then addition because PEMDAS also tells us we should do adding and subtracting from left to right. In this expression, subtracting is on the left side so we should do that first.

16-9.5 = 6.5

6.5 + 4.5 = 11

11 is your answer :)
