I suppose that  when you write "log^6" , you want to say log₆

Change of base formula:
loga b=logc b / logc a

log₆ 120=ln 120 / ln 6=2.67

Answer: log₆ 120=2.67

Equivalent expressions for 7x-6x+4x
Alekssandra [29.7K]

Answer:

<h3>5x</h3>

Step-by-step explanation:

7x-6x+4x ← <em>(Add and subtract elements to the numbers from left to right.)</em>

<em />

7-6+4

PEMDAS- (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) from left to right.

7-6+4 ← (Add & subtract.)

7-6=1

1+4=5

= 5x

5x, which is our answer.

Help please explain as simple as possible
Virty [35]
Short answer: (-8)^2 + 8  x  -8 = 0

Use PEMDAS

"Evaluate the expression" just means solve until you can't simplify anymore. You must solve it in a certain order according to PEMDAS: Parentheses, Exponents, Multiply, Divide, Add, Subtract.

What does the beginning of the expression look like? It is (-8)^{2}.

According to PEMDAS, you must solve what is in the parentheses *first*. But, since there is only a number (-8), there is nothing to solve for and you can move on to exponents.

The squared symbol, the little 2, means you have to square what is *inside* the parentheses. (-8)^{2} = 64, because -8 times itself is 64.

Next comes multiplication. Remember, we are not working from left to right. We must multiply the values on the far right before we do any adding, because multiplication comes *before* addition.

(64) + (8 times -8)

(64) + (-64)

Finally, we can add. In this case, because we are adding a negative number, we are really subtracting. 64 + -64 equals 0.
