Simplify -22 + (-5) x6

1 answer:

3 0

Ok so since we need to simplify -22+(-5)x6 let’s get started
Multiply -5 by 6
-22-30

Therefore the answer will be -52.

I’m still confused if you’re either assuming the variable x or the multiplication sign (x). So if you’re doing an algebra problem just be sure to use parentheses when you’re dealing with multiplication.

One way you could solve this is to just multiply the top and bottom out so that you get 9/81, reducing it by 9/9 to get 1/9 or option C.
Another way would be to do $3^{(2-4)}$ since dividing numbers with exponents would be subtracting the bottom exponent from the top exponent, provided that the base number (in this case 3) is the same for both. For this method, you would get $3^{-2}$ , which is equal to 1/9 or .1 repeating, the same answer that you'd get with the first method.
