15⋅8^0/5+4(7^0−6) .

Answer 1

To solve this expression, we need to follow the order of operations (also known as PEMDAS/BODMAS).

First, we solve any operations within parentheses. The expression does not have any parentheses except for 7^0.

Any number raised to the power of 0 is 1. So, 7^0 = 1.

Now the expression becomes:

15⋅8^0/5+4(1−6)

Next, we solve any multiplication or division from left to right. First, we solve 8^0.

8^0 = 1

Now the expression becomes:

15⋅1/5+4(1−6)

Next, we solve any addition or subtraction from left to right. Since there are no addition or subtraction operations remaining, we move to multiplication and division.

15⋅1 = 15

Now the expression becomes:

15/5+4(1−6)

15/5 = 3

Now the expression becomes:

3+4(1−6)

Next, we solve the subtraction inside the parentheses.

1 - 6 = -5

Now the expression becomes:

3+4(-5)

Next, we solve the multiplication.

4 * -5 = -20

Now the expression becomes:

3+(-20)

Finally, we solve the addition.

3 + (-20) = -17

Therefore, the value of the expression 15⋅8^0/5+4(7^0−6) is -17.
